Integral analysis based diagnostics of turbulence model errors in skin friction
Shyam S. Nair, Vishal A. Wadhai, Robert F. Kunz +1
Error diagnostics for turbulence models have traditionally focused on engineering quantities of interest, such as the skin-friction coefficient, , most often by comparing the…

Rough surfaces in under-explored surface morphology space and their implications on roughness modelling
Shyam S. Nair, Vishal A. Wadhai, Robert F. Kunz +1
We report direct numerical simulation (DNS) results of the rough-wall channel, focusing on roughness with high statistics but small to negative statistics, and w…
