The turbulent boundary layer: An experimental study of the transport of momentum and heat with the effect of roughness

Marcos M. Pimenta, Robert J. Moffat, W. M. Kays

Abstract

The turbulent boundary on a deterministic rough wall has been examined for the cases of isothermal and non-isothermal, zero pressure gradient flows with and without transpiration. The data include temperature and velocity profiles, turbulence intensity profiles, turbulence shear stresses and heat flux profiles and the correlation coefficients of both the fluid dynamic and temperature fields.
