The main goal of the present study is to perform LES of fully compressible turbulent channel flows at low-Mach number (M<0.2) and Reτm= 400 at different temperature gradients between the walls (Tcold/Thot}= 1.01, 2 and 5) to analyze the temperature gradient effects on the flow re-laminarization and the enhanced heat transfer mechanisms.
