Download or read book A Correlation of Heat transfer and Skin friction Data and an Experimental Reynolds Analogy Factor for Highly Cooled Turbulent Boundary Layers at Mach 5 0 written by Donald M. Wilson and published by . This book was released on 1969 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulent boundary-layer heat transfer and skin-friction coefficients were measured on sharp slender cones at a free-stream Mach number of 5.0. Wall-to-stagnation temperature ratios from 0.15 to 0.80 were obtained by precooling or preheating the model. Tests were conducted for a wide range of Reynolds numbers by varying the tunnel supply pressure and temperature, thus providing data for naturally turbulent boundary layers. The experimental results were compared with existing theories which predict convective Stanton number or skin-friction coefficients. These comparisons indicate that the heat-transfer data are best predicted by the Spalding-Chi law and the skin friction by the Sommer-Short reference temperature method. The experimental Reynolds analogy factor is adequately predicted by Colburn's incompressible correlation for wall-to-stagnation temperature ratios above about 0.5. However, for lower wall temperature ratios, the experimental Reynolds analogy factor decreases with decreased temperature ratios in a manner which has not been previously reported. (Author).

This book was released on 1952 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The method presented in NACA TN 2692 for evaluating the skin friction of a turbulent boundary layer in compressible flow on an insulated surface is extended to evaluate the turbulent skin friction and heat transfer in compressible flow on a surface which is heated or cooled. The results of this analysis are in good agreement with the heat transfers measured in flight on the NACA RM-10 missile up to Mach number of 3.8.

This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was made of the effect of a favorable pressure gradient on the Reynolds analogy factor, K = 2St/C sub f, for a natural two-dimensional supersonic turbulent boundary layer in air. Integrated values of the skin friction coefficient and Stanton number were determined from experimental data. The results show that Colburn's value of K = Pr to the - 2/3 power, which was found empirically from zero pressure gradient data, is satisfactory for relating skin friction and heat transfer for the magnitudes of pressure gradients investigated.

This book was released on 1954 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previous report, NACA TN 3007, gave force and moment data for the NACA 64A010 airfoil section equipped alternately with a flap and a slat at the leading edge, and with a split flap and a double-slotted flap at the trailing edge. The present report presents the chordwise distributions of pressure measured concurrently with the force and moment data of NACA 3007. The pressure data for the leading-edge flap and slat have been converted into coefficients of normal force, chord force, and moment based on the geometry of the leading-edge device.
