Abstract

A fully developed square channel flow with a Reynolds number of Re=4410 (based on bulk velocity and duct width) has been calculated using Large Eddy Simulation (LES) technique with the Smagorinsky eddy viscosity model. Results for the Prandtl’s secondary motion which is turbulence-driven show good qualitative picture and are in good quantitative agreement with values from other authors. Different numerical aspects have been investigated: the size of the numerical grid, the spatial discretization scheme for convection, the time discretization with first- and second-order implicit schemes. The accuracy of the results as well as the resources required for all cases studied are compared and discussed in detail.
