摘要：
This paper: (i) discusses an algorithm that addresses the problems posed by low Mach numbers and high Reynolds numbers in large-eddy simulation of compressible turbulent flows, (ii) uses numerical solutions of the RDT equations to suggest the possibility that the linear effects of pressure might be more important to model in the near-wall problem, than nonlinear transfer, and (iii) a simple kinematic model that possibly explains why large-eddy simulation predicts turbulent mixing accurately, even though the viscous processes are not being represented. © Springer-Verlag Berlin Heidelberg 2007.
