概要	This paper reports the development of a refined wall-function strategy for the modelling of turbulent flow over rough surfaces. In order to include the effects of fine-grain surface roughness, the present study extends a more fundamental work previously carried out at UMIST on the development of advanced wall functions of general applicability The presently proposed extension is validated through comparisons with data available for internal flows through rough pipes, channels and for external flows over rough surfaces. Then, its further validation in separating flows over a sand dune and a sand-roughened ramp is discussed. The validation results suggest that the presently proposed form is successfully applicable to a wide range of attached and separated turbulent flows over fine-grain rough surfaces.
