SINOPSIS

The Reynolds-averaged Navier-Stokes approach will continue as the primary methodology used in the foreseeable future for the numerical solution of complex turbulent fluid flow problems. With this continuing demand and the continuing increase in computational capabilities, higher-order closures, such as algebraic and differential Reynolds stress models, will be more extensively utilized. Even though such closures are currently available, modeling improvements will be required in a variety of terms that appear in these formulations to satisfy the ever-increasing accuracy requirements. Beyond these approaches, as computational capabilities increase, will be the trend toward the "direct" solution of turbulent flow fields. In the interim, however, composite methods, that bridge the gap between partial and total resolution of the turbulence scales, will be required.
