In this paper, the performance of the optimized symmetric fourth-order weighted essentially non-oscillatory scheme (WENO-OS4) in direct numerical simulation of compressible turbulence is demonstrated and compared with other three optimized WENO schemes. The compressible homogenous turbulence and channel flow with different Mach numbers and Reynolds numbers are employed to assess the dispersion and dissipation relation of WENO-OS4 scheme. And the shock wave/turbulent boundary layer interaction is directly simulated to access the ability of WENO-OS4 of simulating complex compressible turbulence with large-scale separation. The detailed turbulent structures and the shock waves are obtained. The mean profiles and other statistical data are precisely computed. This study demonstrates the capability of the WENO-OS4 and other optimized WENO scheme for DNS of compressible turbulence.
