Abstract

A turbulent flow in a square pipe is investigated through a direct calculation of the discretized Navier-Stokes equations based on the control volume method. The direct numerical calculation approach is essentially free from any turbulence model. The computational results in this study are compared with the other experiment and the large eddy simulation (LES) results. It has revealed that the present calculation predicts the characteristic feature of the turbulent flow even with the coarse grid system, and quantitative improvement of the solution is achieved nearly in proportion to the grid resolution squared.
