Numerical simulation of the turbulent Couette flow based on the quasi-gasdynamic equations
Abstract:
The numerical simulation of the turbulent and laminar channel Couette flow is performed by means of the quasi-gas dynamic (QGD) algorithm for the viscous compressible gas flow. The results show good agreement with experimental and calculated data obtained previously. It is shown that the QGD algorithm gives opportunity to simulate turbulent and laminar near-wall flows universally. Besides, the QGD algorithm demands smaller number of the spatial grid than the standard DNS methods of high approximation order.
