Unsteady Turbulent Flows

Part of the Springer Series in Computational Physics book series (SCIENTCOMP)


The problem of turbulence is certainly one of the well-known “unsolved” problems in mechanics. It has challenged some of the most respected scientists of our times. New physical concepts have thus been invented, and the efforts to understand the problems stimulated the development of elegant stochastic theories. However, such methods are far from producing meaningful engineering results for practical problems. The designer still relies on heuristic phenomenological models that may appear almost arbitrary to the rigorous analyst. It is within this framework that we introduce here one more dimension in the problem that further increases its complexity: time dependence.
