Turbulent flow over transitionally rough surfaces with varying roughness densities
M. MacDonald, L. Chan, D. Chung +2
We investigate rough-wall turbulent flows through direct numerical simulations of flow over three-dimensional transitionally rough sinusoidal surfaces. The roughness Reynolds numbe…
Direct numerical simulation of high aspect ratio spanwise-aligned bars
M. MacDonald, A. Ooi, R. García-Mayoral +2
We conduct minimal-channel direct numerical simulations of turbulent flow over two-dimensional rectangular bars aligned in the spanwise direction. This roughness has been often des…
Application of a POD-Galerkin based method to time resolved and time unresolved data for the determination of the Convective Velocity of Large-Scale Coherent Structures in High Speed Flows
Tushar Sikroria, Julio Soria, Richard Sandberg +1
Motivated by the aero-acoustic feedback loop phenomenon in high speed free jets and impinging jets, a thorough examination of a POD (Proper Orthogonal Decomposition)-Galerkin metho…
