Laminar and turbulent regimes of the Taylor-Green vortex decay
Abstract:
The numerical simulation of the classical TaylorGreen flow problem is performed by means of the quasi-gasdynamic (QGD) algorithm for the viscous compressible gas flow simulation. It is shown that the QGD algorithm gives opportunity to model turbulent (at large Reynolds number) and laminar (at small Reynolds number) flows universally. Besides, the QGD algorithm demands smaller number of the spatial grid than the standard direct numerical simulation methods of high approximation order.
