What is High Reynolds Number Flow Simulation about?

This document summarizes a numerical study of flow around a smooth circular cylinder at very high Reynolds numbers (Re = 1x106, 2x106 and 3.6x106) using a 2D URANS model with a standard k-ε turbulence model. The results are compared to experimental data and other numerical studies. While the k-ε model is known to be less accurate for flows with strong anisotropic turbulence, the study finds that satisfactory results for engineering design purposes are obtained for flows in the supercritical and upper-transi
