Roughness effects in Head's integral boundary-layer method
Abstract
A simple procedure for including surface roughness effects in Head's momentum integral entrainment method is presented. A correlation by Finson (1982) relating equivalent sand-grain height to roughness height, spacing, and shape is used to generate rough-wall skin friction and thicknesses from Head's entrainment method. Good agreement is obtained with the rough-wall data sets of Coleman (1976) and Healzer et al. (1974).
