Abstract
A Chebyshev multidomain staggered-grid method (CMSM) presented by Kopriva for numerical simulation of three-dimensional compressible turbulent flows, is validated. Computations with the CMSM of an isotropic turbulence and a fully developed turbulent channel flow are compared with previously published results. Turbulence initiation of the isotropic turbulence on the Chebyshev grid is discussed. Low-resolution simulations ensure transition of an initial laminar channel flow to a turbulent channel flow. The turbulent kinetic energy spectrum has sufficient dropoff (indicating a resolved solution) at a minimum of 3 to 6 points per wave number for a polynomial approximation of 13 to 10, respectively
