Abstract

A survey is presented for current status of hydrodynamically unsteady turbulent flow modeling in channels as well as some results obtained to date. The hydrodynamically optimal shape of flow acceleration curve is derived. An analytical solution is obtained for the Prandtl friction ratio equation. Numerical simulation results are provided for turbulent flow in a circular pipe using modem turbulence simulation techniques.
