This book was released on 1959 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a survey of theoretical and experimental determinations of the effect of slip flow on skin friction and heat transfer. Both the theoretical and experimental results indicate that for a given axial pressure gradient, slip effects can be correlated as a function of the local Knudsen number based on boundary layer thickness. An approximate method of estimating slip effects is suggested for practical flight shapes having axial pressure gradients. Quantitative evaluation of slip effects for a flat plate and a hemisphere in hypersonic high altitude flight indicates that slip effects are overshadowed by other low density effects such as transverse curvature and viscous interaction between the shock wave and boundary layer.

Available in PDF, EPUB and Kindle. Book excerpt: Experiment have been conducted to measure the local surface-shear stress and the average skin-friction coefficient in incompressible flow for a turbulent boundary layer on a smooth flat plate having zero pressure gradient. Data were obtained for a range of Reynolds numbers from 1 million to 45 million. The local surface-shear stress was measured by a floating-element skin-friction balance and also by a calibrated total head tube located on the surface of the test wall. The average skin-friction coefficient was obtained from boundary-layer velocity profiles.

This book was released on 1964 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work done on the use of the surface impact probe, or Preston tube, method of measuring skin friction in turbulent, compressible boundary layers. The theory for incompressible flow was extended to the case of adiabatic, compressible flow, and the extended theory was experimentally shown to be valid. It has also been demonstrated that the extension is applicable to adiabatic flow with moderate adverse pressure gradients. Experimental and theoretical efforts to apply the impact probe method to compressible flows with moderate, aerodynamic heating were only partially successful. (Author).

Download or read book Practical Aspects of Calculating Skin Friction Coefficients by Coles Theory of Compressible Turbulent Flows written by J. L. Raymond and published by . This book was released on 1967 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coles' theory for the turbulent boundary layer in a compressible fluid is used to compute curves of skin friction coefficient versus Reynolds number. The Mach numbers and wall-temperature ratios selected provide sufficient information for rapid estimation of turbulent skin friction drag for flat plates with zero pressure gradient. These results, though limited in scope and unverified experimentally for conditions outside the range of data originally considered by Coles, nevertheless provide the practicing aerodynamicist with a relatively simple means of estimating the flat-plate skin friction for airplane or missile components having compressible turbulent boundary layers. Coles' theoretical hypotheses, partly based on experimental data, may be of significant value in improving upon the more exclusively empirical treatments of the past. While not difficult to interpret, Coles' equations are mathematically complex and contain thought-provoking physical reasoning. In addition to the calculations of skin friction, the study includes a discussion of Coles' classical theory and an interpretation of it for practicing aerodynamicists. The machine program for JOSS, The RAND Corporation's on-line interactive computing system, is included. (Author).
