Comparison between discretization schemes in direct numerical simulation of turbulent flow through a square pipe

Research output: Contribution to journal › Article › peer-review

Abstract

A direct numerical simulation has been conducted for turbulent flow through a square pipe. Turbulent flow solutions are obtained using the 2nd order accurate central difference scheme as well as Leonard's QUICK scheme for discretizing convective terms on three grid systems of different resolution. Comparison between the results has revealed that the QUICK scheme provides more accurate results with less computational effort than the central difference scheme. In the present condition, the solution for the QUICK scheme converges monotonically with increasing number of grid points, while the result for the central difference scheme shows rather complex behavior.
