Importance

Computational Fluid Dynamics (CFD) is an area in which the governing equations for fluid flow are solved in discrete form on computers by simulating the fluid flow problem. This helps in reducing the time and effort required in narrowing down on the design configurations of various engineering components. The use of CFD can also help in enhancing the quality of the products, as the designers can look at the product from all possible angles before prototyping it. For example, in case of engineering equipments like industrial heat exchangers, the design can be optimized by the use of CFD to save energy in operation, which is a very vital and precious input for design industries. A realistic CFD problem simulation to resolve all possible phenomena places very high demands on speed and memory of the computer systems. It has been proved quite convincingly that the only way to perform such computations is by the use of parallel computers. In the case of aircraft design the time to arrive at an efficient aerodynamic configuration can be reduced by orders of magnitude by performing simulations.
