Comparison between discretization schemes for numerical analysis of turbulent flow in a square pipe
Abstract
A numerical analysis has been conducted for the turbulent flow through a square pipe in relatively coarse grid systems. Turbulent flow solutions were obtained using the central differencing and the Leonard's QUICK (Quadratic Upstream Interpolation for Convective Kinematics) scheme for discretizing the convective terms. The mean velocity field for each result successfully predicted the typical secondary flow motion. Mean axial flow converges monotonically with the grid refinement for the QUICK case, while it has an extremum value for the central difference case.
