Abstract

The use of Computational Fluid Dynamics (CFD) is a common factor in the technical design industry these days. For example, the design of rockets, airplanes and Formula 1 cars would not be the same without CFD. When only the averaged drag coefficient or the averaged forces are needed, time independent simulations are sufficient. However, for a lot of applications knowing only the averaged values is not sufficient. One can think of the unsteady flow that comes from the central core of a space launcher which creates unsteady forces on its nozzle during take-off. Knowing only the averaged values makes it impossible to create a cost effective space launcher which is strong enough to withstand those unsteady forces. For those problems time dependent computations are necessary.
