The study of fluid flow using numerical techniques and algorithms is the focus of the engineering and physics field known as computational fluid dynamics (CFD). It involves simulating the behavior of fluids, including liquids, gases, and multiphase flows, using mathematical models and computer algorithms.
Numerous phenomena, such as fluid flow in pipes, heat transfer, combustion, turbulence, and aeroacoustics, can be studied using CFD. It is a very interdisciplinary field that uses concepts from computer science, physics, and mathematics.
To solve the equations governing fluid flow, CFD software programs typically combine numerical techniques like finite volume, finite element, and spectral methods. The Navier-Stokes equations and other equations that describe the behavior of particular types of fluids, such as the ideal gas law for compressible flows, are some examples of these equations. They describe how fluid motion changes in response to forces and pressure gradients.
In general, CFD is an effective tool for engineers and scientists to research and resolve fluid flow issues in a variety of applications, from the design of vehicles and aircraft to the study of chemical and biological processes.
