Download or read book Influence of Surface Roughness on the Second Order Transport of Turbulence in Non-Equilibrium Boundary Layers written by and published by . This book was released on 2006 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal objective of this project was to gain improved understanding for the mean and turbulent flow physics associated with non-equilibrium, strained, supersonic, compressible boundary layer flow over rough curved surfaces and elevated freestream turbulence levels. Measurements of mean flow and turbulence statistics within such boundary layers has been conducted using Particle Imaging Velocimetry (PIV) technique and the data are reported. Numerical simulation of the flow was also conducted using the eddy-viscosity turbulence models and comparison of the predictions with measurements was performed and reported. This report consists of two parts. The experimental work in this project was subcontracted to R.D.W. Bowersox, Aerospace Engineering Department, Texas A & M University, TX. In Part I, the experimental work done by Bowersox and his group is reported. The pertinent experimental data is given at the end of Part I of this report. The numerical simulation is reported in Part II of this report.
