Introduction

Bioengineering, often known as healthcare and biomedical engineering, is a multidisciplinary STEM area that integrates biology and engineering to apply engineering ideas and materials to medicine and healthcare. The increase in demand for Biomedical Engineers is linked to society’s overall shift toward using machines and technology in many parts of life. Combining engineering principles with biological knowledge to solve medical demands has resulted in the development of groundbreaking and life-saving innovations such as artificial organs, surgical robots, advanced prosthetics, new pharmaceutical medications, and kidney dialysis.

Biomedical Engineering is a vast discipline with several areas of specialization, and the kind of work you’ll be doing will vary depending on your role’s characteristics. Biomedical Electronics, Biomaterials, Computational Biology, Tissue, and Genetic Engineering, Medical Imaging, and Orthopedic Bioengineering Bionanotechnology are only a few of the sub-disciplines of Biomedical Engineering.

How to Improve Biomedical and Healthcare Engineering using CFD Simulations?

Biomedical computing advances have altered the face of biology and medicine in research and clinical practice. The advantages of biomedical computing are numerous and varied. They are critical in gaining a better understanding of human physiology, enabling exciting new biomedical discoveries, and assisting in developing new clinical treatments. In the biomedical field, several numerical approaches are utilized for simulation purposes. For structural analysis, methods such as the Finite element method (FEM) are used. For example, stress analysis of the human skull during the head collision or studying stress distribution in hip implants, to name a few examples. Computational fluid dynamics techniques aid in understanding fluid motion in and around the body. CFD is used in the biomedical area to analyze blood flow in arteries, simulate airflow in the respiratory passages, etc.

Thermal analysis is another interesting method that helps understand the heat transfer mechanism between various body parts and the external environment. Thermal analysis of cooling a human heart during cardiac surgery is one such application. Another critical simulation approach is multi-body dynamics, which aids in understanding human biomechanics. This is especially useful when comprehending the movements of a physically impaired or injured person. The optimization technique is the most recent technology in biomedical computing. Optimization algorithms are now used for improving the designs of medical devices implanted in patient bodies. Optimization of patient-specific stents and hip implants are some common examples.

CFD on Reducing Dispersion of the Microdroplets Containing the Virus

COVID-19 pandemic has started a big challenge to the world health and economy in recent years. Many efforts were made to use the CFD approach in this pandemic. CFD was used to understand the airborne dispersion and transmission of this virus in different situations and buildings. The CFD modeling studied the effect of the various conditions of the ventilation to discuss preventing COVID-19 transmission. Social distancing and using the facial masks were also modeled by the CFD approach to study the effect on reducing dispersion of the microdroplets containing the virus.

CFD applications for modeling COVID-19 spreading in an airplane cabin, an elevator, a small classroom, an operating room of a hospital, a restaurant, a hospital waiting room, and a children’s recovery room in a hospital can be discussed in different scenarios. CFD modeling for studying the effect of social distancing with various spaces, using and not using facial masks, the difference between sneezing and coughing, different inlet/outlet ventilation layouts, combining air-conditioning and sanitizing machines, and using general or local air-conditioning systems are of the application of CFD simulation in biomedical engineering.

 

CFD for Cancer Removal

Intra-Arterial Chemotherapy is a preferred treatment for primary liver cancer, despite its adverse side effects. During IAC, a mixture of chemotherapeutic medicines, e.g., Doxorubicin, is injected into an artery supplying the tumor. The tumor absorbed a fraction of Doxorubicin, but the remaining drug passed into the systemic circulation, causing irreversible heart failure. The effectiveness and safety of the IAC can be improved by chemical filtration of the excessive drugs with a catheter-based Chemofilter device, as proposed by a team of neuroradiologists.

Computational Fluid Dynamics (CFD) modeling can be used to optimize the hemodynamic and drug binding performance of the Chemofilter device.

Simulation of Various Vessels in CFD

The use of image-based models and computational fluid dynamics to simulate blood flow has found significant use in assessing hemodynamic parameters related to the onset and progression of cardiovascular illnesses and designing therapies. CFD can provide flow visualization to show flow phenomena such as recirculation. Simulations can also provide valuable metrics for quantitative analysis, allowing comparison between anastomosis techniques.

CFD results can also highlight regions of high shear stress, in which red blood cell damage can occur. A key advantage of CFD over experimental approaches is that all flow properties are inherently calculated throughout the entire simulated domain.

This article covered a small number of CFD applications in improving biomedical and healthcare engineering. The healthcare industry is full of applications for CFD. From the Dyspnea arteries or the effect of the Eclipse of the vessels on the pressure distribution. Fluid dynamics are fundamental to most facets of the biomedical and healthcare sector. Although real prototypes are standard for later stages of development, design, and optimization during earlier stages can be significantly accelerated with CFD studies.

MR-CFD Services

The MR-CFD team conducted numerous outsourced simulation projects for industrial and research biomedical and healthcare engineering applications. With several years of experience simulating a wide range of problems in various CFD fields using ANSYS Fluent software, the MR-CFD team is ready to offer extensive services of simulation configurations. For example, the simulation of Blood Flow in Clogged Arteries, which depicts how blood behaves when there is a curved blockage in the center of the blood flow stream as an indication of clogging, is one of the studies freelanced and carried out by MR-CFD that has major applications.

CFD was used to design and equip a specific operating room with ventilation, and air conditioning equipment, in another example. When the patient inhales and exhales, he receives oxygen and exhales carbon dioxide.

The core objective of this simulation is to allow fresh air (oxygen-carrying) to flow continually into the interior of the room rather than contaminated air to be expelled into the environment via the patient’s mouth. Fresh air is circulated inside the room via ventilation systems and air conditioners installed on the ceiling and floor, directing it from the side pores to the outside environment.

Common methods of cancer treatment include surgery, radiotherapy, and Chemotherapy. These methods have disadvantages, including aggressiveness, irreversibility, and side effects. Warming in Hyperthermia Therapy prevents oxygen and nutrients from getting into the unhealthy tissue; in this way, proteins within the tissue change nature and surround the cancer cells. This makes it possible for the immune system to identify cancer cells.

The ANSYS Fluent Software can be used to simulate this model. The following study used Hyperthermia Therapy to analyze blood flow in capillaries passing through a tissue containing malignant tumors. We’ll use a spherical sphere to represent a healthy human tissue or cell with very slow blood flow.

There are four spherical cancerous tumors of different diameters at the center of this tissue and on the surface of the veins as Biological Tissue. This study investigates the response of blood vessels and body tissues to this heat.
