Abstract: Direct numerical simulation (DNS) of wall-bounded compressible turbulence is performed. Our main objective of this study is to clarify compressible effects on turbelence near adiabatic and isothermal walls. Compressible supersonic turbulent flow simulations in a plane channel between isothermal walls, and between isothermal and adiabatic walls are performed. The governing equations of compressible fluid flow are solved using B-spline collocation method in the wall normal direction with Fourier Galerkin method in the periodic directions. As a typical result, the peak value of streamwise velocity fluctuation near the adiabatic wall becomes smaller than one near the isothermal wall in wall coordinates.
