Computational Fluid Dynamics (CFD) (CFD)
CFD is one of the branches of fluid mechanics, which uses numerical analysis and numerical algorithms, analyzes issues involving fluid dynamics. Computers are used to simulate the interaction of fluids and gases with boundary conditions. This branch of fluid mechanics connects old mechanics to computer science and its new computational abilities in the second half of the twentieth century and in the new century.
In this method, by converting certain differential equations governing the fluids into algebraic equations, numerical solution of these equations can be provided. By dividing the desired region into smaller elements and applying boundary conditions for boundary nodes, approximations of a linear equation system are obtained. By solving this system, the algebraic equations, the velocity, pressure, and temperature fields are obtained in the desired region. Using the results obtained from solving the equations, we can calculate the effects of input forces on the levels, the coefficients for and after, and the heat transfer coefficient.
