摘要: Recently, with the advent of supercomputers, there has been considerable interest in the use of direct numerical simulation to obtain information about turbulent shear flow at low Reynolds number. This paper presents a pseudospectral technique to solve the full three‐dimensional time‐dependent Navier‐Stokes and advection‐diffusion equations without the use of subgrid‐scale modelling. The technique has not been previously used for fully developed turbulent channel flow simulation and is based on methods applied in other …
