Book Description
A second-order closure technique for the compressible turbulent boundary layer equations has been developed. The technique is employed in the calculation of boundary layers with surface injection of similar and foreign gases. Theoretical results for M approximately 3 and several air injection rates provide favorable comparison with experimental data. Theoretical mean velocity and mass fraction profiles for a propane injected oxygen boundary layer are also presented. The additional ability of the technique to accommodate finite rate chemical reactions in a multi-species system was investigated. Preliminary results are provided for the rapidly developing region of flow downstream of an ignition and turbulence source. Application of the closure technique to the calculation of a variety of reacting shear flows is currently being performed at ARAP.

Book Description
Analysis of Turbulent Boundary Layers focuses on turbulent flows meeting the requirements for the boundary-layer or thin-shear-layer approximations. Its approach is devising relatively fundamental, and often subtle, empirical engineering correlations, which are then introduced into various forms of describing equations for final solution. After introducing the topic on turbulence, the book examines the conservation equations for compressible turbulent flows, boundary-layer equations, and general behavior of turbulent boundary layers. The latter chapters describe the CS method for calculating two-dimensional and axisymmetric laminar and turbulent boundary layers. This book will be useful to readers who have advanced knowledge in fluid mechanics, especially to engineers who study the important problems of design.

Book Description
The paper describes the results of a detailed experimental investigation of a two-dimensional turbulent boundary layer in a favorable pressure gradient where the free-stream Mach number varied from 3.8 to 4.6 and the ratio of wall to adiabatic-wall temperature has a nominal value of 0.82. Detailed profile measurements were made with pressure and temperature probes; skin friction was measured directly with a shear balance. The velocity- and temperature-profile results were compared with zero pressure gradient and incompressible results. The skin-friction data were correlated with momentum-thickness Reynolds number and pressure-gradient parameter. (Author).
