ABSTRACT
Computational uid dynamics (CFD) is a mechanical engineering eld that deals with analyzing uid ow, heat transfer, and associated phenomena, using computer-based simulation. CFD is a widely adopted methodology for solving complex problems in many modern engineering elds. e merit of CFD lies in the development of new and improved devices and system designs, and existing equipments are optimized through computational simulations, resulting in an enhanced eciency and lower operating costs. However, in the biomedical eld, CFD is still emerging. e main reason why CFD in the biomedical eld has lagged behind is the tremendous complexity of human body uid behavior. Recently, CFD biomedical research is relatively easy and possible, because high-performance hardware and soware are easily available with advances in computer science. All CFD processes contain three main components to provide useful information, namely, preprocessing, solving mathematical equations, and postprocessing. Initial accurate geometric modeling and boundary conditions are essential to achieve adequate results.
