Coronavirus CFD Simulation Training Package

Coronavirus Dispersion CFD Simulation Training Package by ANSYS Fluent, 10 Practical exercises

Coronavirus (COVID-19) is currently recognized as the greatest and the newest human challenge in the world. In addition to being dangerous to human health, coronavirus has a high transmission power between sick people and healthy people. Breathing of a patent person without a mask into an enclosed space can transmit the disease to nearby people. Although, coughing and sneezing are dramatically more dangerous, even in the open air.

One of the important recommendations of doctors regarding the prevention of coronavirus particle transmission between people, is social distancing in different places, including public transportation, hospital, school, stadium, restaurants, and so on. The social distance can be different in various locations in terms of being indoors and outdoors.

Air conditioning systems play the main role in virus infection removal. So we need an accurate and practical air conditioning system design to overcome the virus particle dispersion in different places like airplanes, elevators, clean rooms, operation rooms, open-air, and so on.

In this CFD simulation training package, we will enlighten you on the essential tact to carry out numerical CFD simulations. We investigate both steady and transient solvers, breathing, coughing, and sneezing of patients in different places of an airplane cabins, elevator cabins, clean rooms, operation rooms, cars, classrooms, and open air. The coronavirus spread CFD simulation training package includes 10 different CFD projects by ANSYS Fluent including comprehensive training movies and simulation files.

This CFD training package is prepared for BEGINNER, INTERMEDIATE, and ADVANCED users of ANSYS Fluent software who are interested in the Coronavirus subject, including 10 practical exercises. You will learn and obtain comprehensive training on how to simulate projects. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

Coronavirus (COVID-19) is currently recognized as the greatest human challenge in the world; Because this disease, in addition to being dangerous to human health, has a high transmission power between sick people and healthy people. Breathing of a patent person without a mask into an enclosed space can transmit the disease to nearby people. One of the essential recommendations of doctors regarding the prevention of disease transmission between people is to maintain social distancing in different places, including public transportation.

Project number 1 simulates the airflow from a patient’s (COVID-19) mouth in a hospital room. In fact, in the present case, a special operating room has been designed and equipped with ventilation and air conditioning systems. On the other hand, the patient receives oxygen and exhales carbon dioxide every time he inhales and exhales.

In project number 2, an attempt has been made to simulate the respiration of viral air from the mouths of several patients carrying coronavirus in the aircraft. This model includes a computational domain in the form of an airplane and seats inside it, on each of which a passenger is modeled.

The elevator cabin is one of the most important spaces in the discussion of coronavirus disease; Because usually, some people with the shortest possible distance are placed in a small space with a not very strong ventilation system. In project number 3, based on the CFD method, an attempt has been made to simulate the coronavirus particle dispersion from the carrier patient’s cough inside an elevator cabin.

Project number 4 involves a human placed in a cube-shaped computational domain in the open air. The human mouth is distinguished as a source of virus transmission. To simulate this model, a discrete phase model must be used. This model allows us to study a set of discrete particles in a continuous fluid space. In this model, the wet particles of the virus secreted from the patient’s mouth are defined as a discrete phase and the airflow as a continuous phase in space.

Project number 5 simulates the flow of fresh air through the air conditioning system inside a patient’s room, considering the CORONA virus. We place the patient on a bed in a room with a high temperature on his body and constantly spread the CORONA-virus particles by breathing through his mouth into the room’s interior.

One of the important recommendations of doctors regarding preventing the transmission of disease between people is to maintain social distance between people in small, closed spaces. The interior of a passenger car can transmit the virus to its occupants. In project number 6, based on the CFD method, an attempt has been made to simulate the release of virus particles from the mouth of a corona carrier patient inside the interior of a car.

In project number 7, a ventilation system has been used, which has several vents for the entry of fresh air flow from the ceiling of the classroom and several panels for the exit of the old airflow at the bottom of the classroom sidewalls.

Project number 8 investigates the ability of coronavirus particles to spread inside the bank from a bank customer to a healthy bank employee. This simulation process is performed in two different modes. In the first model, no cover is located between the client and the bank employee to show the virus’s transmission power. In the second model, an attempt is made to make a thin plastic cover between them. The cover should be defined to demonstrate the process of preventing the transmission of virus particles as a barrier.

In project number 9, based on the CFD method, an attempt has been made to simulate the release of virus particles from a Coronavirus patient’s mouth while Talking and transmitting it to another person in a specific space (social distancing). This study aims to investigate the ability of virus particles to propagate and transmit at a distance less than a social distance.

Project number 10 aimed to evaluate the effectiveness of using a shield or mask as a baa patient’s face patient against the spread of virus particles. For the present simulation, the discrete phase model (DPM) is used; Because this model allows us to study the particle’s mass discretely in a fluid space with a continuous phase. Due to the choice of this model, the virus particles secreted from the patient’s mouth are considered a discrete phase, and the open airflow in the computational area is considered a continuous phase.
