Predicting mean profiles in compressible turbulent channel and pipe flows
Yubin Song, Peng Zhang, Zhenhua Xia
Abstract
A robust modular iterative method is proposed to predict the mean profiles in compressible channel and pipe turbulence by solving a nonlinear system using the perfect gas assumption, Sutherland's viscosity law, the variable-property scaling models for compressible wall turbulence, the incompressible velocity law of the wall, and the temperature-velocity relation.
