Book excerpt: A semi-empirical analysis is developed for the over-all flow pattern of subsonic turbulent flow over backward facing steps. Good agrement is found between theory and experiment for the prediction of two-dimensional reattachment length for small values of step height to throat width ratio; an asymptotic solution for large values of step height is also given and discussed. Mean velocity profiles calculated by the present analysis are shown; they require an empirical fit at one point. Good agreement with experiment is found in the region near the step face, but agreement is poor near the reattachment region. Experimental results are represented for flow patterns over backward facing steps covering a wide range of geometric variables. Velocity profile measurements are given for both single and double steps. The stall region is shown to consist of a complex pattern involving three distinct regions. The double step contains an asymmetry for large expansions, but approaches the single-step configuration with symmetric stall regions for small values of area ratio. No effect on flow pattern or reattachment length is found for a wide range of Reynolds numbers and turbulence intensities, provided the flow is fully turbulent before the step. (Author).

This book was released on 1963 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: A first order approximation is derived in similarity coordinates for the velocity variation across a mixing zone between two streams of different velocities in an arbitrary pressure gradient. The velocity profiles obtained are functions of a single parameter, the ratio of the velocity of the slow stream to that of the fast stream. The first order velocity profiles are compared to those obtained from the complete solution to the zero pressure gradient case by Gortler and good agreement is found when the velocity ratio is greater than 0.5. The form of the eddy diffusivity appropriate to the first order theory is determined from analysis and experimental data. This form leads to an explicit transformation for the similarity coordinate requiring only a single empirical constant for all cases. This similarity coordinate is shown to reduce to Gortler's variable in the constant pressure case. Expressions for the shear and the mixing layer width for the general case are presented, and shown to check the data from several cases. A hot wire anemometer which was specially designed and constructed for taking the experimental data in a water channel is described. (Author).
