Energy Balance in a Turbulent Boundary Layer on a Rough Wall

Energy Balance in a Turbulent Boundary Layer on a Rough Wall

Measurements of the mean flow and turbulence fields over a two‐dimensional roughness reveal a shear stress distribution which is very different from that on a smooth wall. The usual mean flow energy equation fails to close indicating other terms may be important.
