Abstract

In an attempt to improve the accuracy in direct numerical simulation (DNS) of fully developed incompressible turbulent channel flow using the finite difference method, the fourth and eighth order central compact schemes with 'spectrallike resolution' have been introduced to the viscous terms, which play an important role in the dissipation range in the near wall turbulence. The DNSs using the conventional second and fourth order central difference schemes are also conducted for comparison. The results are compared with those obtained by the spectral method. The results show the improvement in accuracy by the introduction of the compact schemes. The remarkable improvements in the power and dissipation spectra are also confirmed in the dissipation range.
