CFD AND ITS APPLICATIONS Computational fluid dynamics (CFD) is an aspect of multiphysics system analysis that undertakes the simulation of the behavior of fluids and their thermodynamic properties using numerical models. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by boundary conditions. The first attempt to calculate fluid flow was set forth by Lewis Fry Richardson, with applications for weather prediction. He envisioned a “forecast factory” that included 64,000 human “computers”. Each “computer” was positioned at tiered elevations around a spherical globe, occupying computational cells that corresponded to map locations, for northern Europe. His method involved inputting weather observation data to the corresponding grid locations and then solving the forward-step...
