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 the Moist Stably Stratified Surface Layer: Turbulence and Fog Formation
Michael MacDonald, Marcin J. Kurowski, João Teixeira
We investigate the effects of condensation and liquid water loading on the stably stratified surface layer, with an eye towards understanding the influence of turbulent mixing on f…
Scaling Behavior of a Turbulent Kinetic Energy Closure Scheme for the Stably Stratified Atmosphere: A Steady-State Analysis
Michael MacDonald, João Teixeira
We present a turbulent kinetic energy (TKE) closure scheme for the stably stratified atmosphere in which the mixing lengths for momentum and heat are not parameterized in the same…
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…
