Analytical Study of Turbulent Boundary Layer Development on Rough Surface with Adverse Pressure Gradient.(Dept.M)

One of the purposes of this investigation is to throw some additional light on the question of how to correlate between the experimental data from different sources and the theoretical approaches for the study of incompressible turbulent boundary layers development on rough surface. Moreover, the study developed included the presence of adverse pressure gradient; as well as a discussion about the effect of surface roughness on the boundary layer parameters which control the flow behaviour. On the basis of Zancow experimental work with rough surface and the velocity law of Rotta, this study has been developed. In order to obtain the numerical results for the mathematical solution outlined in this work, a computer program is constructed to perform all the necessary calculations. These results are represented in charts and can be utilised for the geometric shape of roughness.
