Abstract

The Navier-Stokes and Reynolds equations have been numerically solved by a factorized finite-volume method. The Reynolds equations were closed using the Menter shear-stress-transfer model modified with allowance for the curvature of flow lines. The obtained solution has been used to confirm expansion of the range of critical Mach numbers during modeling of a nonstationary flow past a thick MQ airfoil with slot suction in circular vortex cells.
