| Abstract | ||||
| COLES [1] suggested to represent the velocity distribution in turbulent boundary layers with adverse pressure gradient over smooth surface by a linear combination of two universal functions.one is the well known law of the wall, the other the law of the wake which is characterised by the profile at a point of separation or reattachment. The aims of this investigation are to modify Coles velocity distribution to perform the calculations for turbulent boundary layers over smooth and rough surfaces and also to study analytically the various boundary layer parameters and surface roughness function derived from the modified velocity distribution and experimental results with flows over rough surfaces given in [10]. | ||||
