Direct numerical simulation of compressible turbulence in a counter-flow channel configuration

We introduce a counter-flow turbulent channel configuration, amenable to simulation and modeling. It has periodic streamwise spanwise boundaries isothermal no-slip walls. A tangent hyperbolic forcing function drives the flow in opposite directions on upper lower halves of channel, forming an antisymmetric mean shear velocity profile. Compared conventional flows, is inflectional maximum turbulence intensity relative nearly order magnitude higher. The can sustain high Mach numbers which useful for studying Reynolds number flows.
