In this research, CFD is used to model blood flow in the human heart. The objective is to learn how blood flow influences cardiac function and to identify possible areas for improvement.
A Lumen Blood Vessel (FSI & Non-Newtonian) was simulated in this research, and the simulation results were analyzed using ANSYS Fluent software. This CFD project is carried out and investigated using CFD analysis.
This course will introduce you to the principles of CFD simulation using Ansys Fluent. The course will cover the fundamentals of CFD simulation, such as fluid flow physics, numerical methods for solving equations, and software tools for creating and analyzing results. The application of CFD to the study of lumen blood arteries will also be covered, including the consequences of non-Newtonian behavior and the utilization of FSI (Fluid-Structure Interaction) simulations. The course will feature hands-on exercises to assist students to get expertise with the program and to apply the ideas to real-world challenges.
Ansys Fluent software was used to create this project, which simulates a blood artery with a wall, with the displacement of the wall apparent. We defined the pulse velocity using UDF as the input and air pressure as the output. This FSI simulation was carried out within Fluent.
The Ansys Fluent training course on modeling blood vessels (FSI) with pulse velocity is intended to assist engineers and scientists learn the foundations of computational fluid dynamics (CFD) and how to use Ansys Fluent to simulate blood flow in a vessel. The course introduces the fundamentals of CFD, such as governing equations, numerical techniques, and boundary conditions. It also covers the principles of FSI, such as fluid-structure coupling and the use of the ALE approach. The course also covers how to use Ansys Fluent to simulate blood flow in a vessel, including how to utilize the k-epsilon turbulence model, the ALE approach, and the pulse velocity boundary condition. Lastly, the course covers the post-processing of the results, including the use of contour plots, vector plots, and the use of the particle tracing tool.
To utilize ANSYS Fluent to model non-Newtonian pulsing blood flow in the aorta, the user must first establish the aorta shape and boundary conditions. The intake and outflow velocities, wall shear stress, and pressure drop across the aorta must all be specified. The user must also define the blood’s material qualities, such as viscosity and density.
After defining the geometry and boundary conditions, the user must run the simulation. This involves defining the flow type (laminar or turbulent), the numerical technique for solving the equations, and the time step size. The turbulence model and boundary conditions must also be defined by the user.
After configuring the simulation, the user may run it and examine the results. The data will indicate the distributions of velocity, pressure, and shear stress throughout the aorta. The user may also see the flow patterns and the impact of the pulsing flow on the aorta walls. ANSYS Fluent can model non-Newtonian pulsing blood flow in the aorta, among other challenging fluid flow issues. The user may correctly simulate the flow and evaluate the results with the proper setup and boundary conditions.
This simulation uses ANSYS Fluent software to simulate non-Newtonian blood pulse flow in a vein. This CFD project is carried out and investigated using CFD analysis. Blood, a non-Newtonian fluid, is employed in this simulation. Non-Newtonian fluids have viscosities that vary with response rate, implying that they lack a defined viscosity.
Because the connection between shear stress fluctuations and applied stress rates is nonlinear in this type of fluid, there is no consistent coefficient of fit for viscosity. This transient simulation lasts 0.5 seconds. To mimic the pulse of the blood flow, we use a User-Defined Function (UDF). Because blood flow is not continuous and pulsed, the velocity function must be employed regularly using the User-Defined Function code.
ANSYS Fluent is a strong computational fluid dynamics (CFD) software tool that may be used to simulate the flow of non-Newtonian blood pulse flow in a vein. The program may be used to correctly predict the flow of blood through a vein, taking into consideration the viscosity of the blood, the pressure gradient, and the geometry of the vein.

ANSYS Fluent software is used to model the airflow from a patient’s (COVID-19) mouth in a hospital room. This CFD project is carried out and investigated using CFD analysis. In reality, in this scenario, a specific operating room with ventilation and air conditioning equipment has been built. The patient, on the other hand, obtains oxygen and exhales carbon dioxide with each inhalation and exhalation.
The major goal of this simulation procedure is to enable a continuous flow of fresh air (oxygen-carrying) into the room’s interior rather than expel dirty air from the patient’s mouth to the surroundings. Ventilation systems and air conditioners installed on the ceiling and floor of the room are in charge of circulating fresh air and directing it from the side pores to the outside environment.
Using ANSYS Fluent software, this project replicates the Corona Virus Patient STEADY Breathing in a Clean Room. Air conditioning is required in hospital rooms. These air conditioners can continually circulate fresh air into the room, cleaning the contaminated air surrounding the patient. These air conditioners also provide enough cooling and heating.
A room containing a bedridden patient is explored in this simulation. Coronavirus particles are disseminated to the environment by the patient who has corona. The source of respiratory coronavirus transmission is established as the patient’s mouth. In addition, the patient’s body surface temperature is 308 K, which is one of his disease symptoms. The fresh air from air purification systems removes contaminated air and virus particles from the inside of the space. Second, it aids in the cooling of the patient’s body surface and the creation of thermal comfort for the patient. As a result, various panels on the room’s ceiling are specified for the entrance of fresh air with a temperature of 294 K, and the air exit is likewise from the lower portion of the side walls.
ANSYS Fluent CFD simulation training may be used to replicate a Corona Virus patient’s breathing in a clean room.

The simulation may also be used to assess the room’s air quality, such as the concentration of airborne particles, temperature, and humidity. The simulation may also be used to examine the room’s ventilation system, such as the airflow rate, air pressure, and air temperature. The simulation may also be used to assess the room’s air quality, such as the concentration of airborne particles, temperature, and humidity.

In this scenario, we simulate an operating room HVAC system (heating, ventilation, and air conditioning). This chamber houses the equipment and people, including the doctor and patient, and is air-conditioned.
To cleanse the air in the operating room, the system employs laminar flow. A linear flow known as an air curtain keeps tainted air from entering fresh air. The patient’s body is thought to be the source of the contaminated gases. For the clearing procedure, the incoming air goes from the top to the bottom of the operating room.
This article will teach you how to utilize ANSYS Fluent to simulate an operating room’s HVAC system. The purpose of this tutorial is to walk you through the process of setting up and running a CFD simulation of an operating room HVAC system. The first step is to develop a three-dimensional model of the operation area. This may be accomplished with 3D modeling tools like Autodesk 3ds Max or Blender. The walls, ceiling, floor, and any other things that will be present in the room should all be included in the model.
The following step is to make a mesh for the model. This may be accomplished with meshing software such as ANSYS Meshing. The mesh should be fine enough to capture the intricacies of the area, but not so fine that it takes an inordinate amount of time to solve. After creating the mesh, the following step is to define the boundary conditions. This comprises establishing the intake and exit velocities, temperatures, and pressures. It is also necessary to configure the airflow direction and the turbulence model.
The following step is to prepare the materials for the simulation. This involves determining the density, viscosity, and thermal conductivity of the air. It is also necessary to configure the qualities of the walls, ceiling, and floor. The solver must now be configured. This covers selecting the time step, convergence criterion, and other solver settings. The simulation is then executed as the last stage. This is possible with the ANSYS Fluent solver. The results of the simulation may be viewed and studied once it is completed. This article walked you through the process of setting up and executing a CFD simulation of an operating room HVAC system with ANSYS Fluent.

The elevator cabin is one of the most relevant venues in the subject of coronavirus illness because it typically houses a large number of individuals in a tight area with a weak ventilation system. This study attempted to simulate the dispersion of coronavirus particles from the carrier patient cough within an elevator cabin using the CFD approach and ANSYS Fluent software.
This model contains a computational domain in the shape of an elevator cabin in which two persons are modeled; one is a coronavirus patient who coughs or sneezes, and the other is a person who is a specific distance away from the patient and is exposed to coronavirus particles. The goal of this project is to look at the potential of virus particles to spread within elevators and the possibility of spreading them to other people. Human cough virus particles are physically discharged from the patient’s mouth by evaporating water droplets in space, according to this definition of injection.

These systems may be designed to modify the ventilator rate dependent on the patient’s state, allowing for more accurate control of the ventilation rate. This can assist to limit the danger of over- or under-ventilation, both of which can lead to problems.
Increased Airflow: Increasing the airflow in an ICU ventilation system can help lower infection risk. This may be done by increasing the number of air changes each hour, employing directed airflow, and using air filters to eliminate impurities.
Enhanced Monitoring: Better monitoring systems can assist ensure that the ventilation system is operating correctly and that the patient is getting enough oxygen. This may be accomplished by utilizing sensors to monitor the oxygen levels in the space and notifying workers if the levels fall below or beyond a certain threshold.
Improved Alarms: Enhanced alarms can assist notify workers of any changes in the patient’s condition or breathing system. This can assist ensure that the patient receives the proper quantity of oxygen and that any changes in the patient’s health are treated as soon as possible.
Improved Design: Enhancing the design of the ICU ventilation system can help lower the risk of infection and increase patient comfort. This may be accomplished by utilizing materials that are simple to clean and disinfect, as well as structuring the system to minimize noise and vibration.
