Download or read book Measurements of Hypersonic Turbulent Heat Transfer on a Highly Cooled Cone written by Donald M. Wilson and published by . This book was released on 1967 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulent boundary layer heat transfer rates were measured on a thin-walled slender cone at a free-stream Mach number of 5.0. Wall to stagnation temperature ratios from 0.15 to 0.40 were obtained by pre-cooling the model using liquid nitrogen. Tests at a wide range of Reynolds numbers were conducted by varying the tunnel supply pressure; thus providing data for both laminar and mixed laminar-turbulent types of boundary layers. The experimental results obtained were compared with existing theories which predict convective heat transfer coefficients. These comparisons indicate that the data corresponding to a 760R supply temperature verify the predictions of Winkler and Cha; however, data acquired at a supply temperature of 1160R substantiate the predictions of Spalding and Chi.

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).

Download or read book The Prediction of Errors and the Improvement of Data Obtained in Wind tunnel Heat transfer Tests written by Donald M. Wilson and published by . This book was released on 1970 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of heat-transfer data in a high-speed wind tunnel is considered in detail. The analysis is restricted to tests where transient temperature measurements are made by thermocouples attached to the back face of a thin-walled model. Methods of estimating the error in obtaining a heat-transfer coefficient due to extraneous heat-transfer rates or the choice of a data-reduction method are presented. The error caused by the presence of a thermocouple in a thin wall was found experimentally. Methods of improving heat-transfer data, including the Thomas-Fitzsimmons conduction correction method, are discussed. (Author).

Download or read book A Digital Computer Program for Making Comparative Aerodynamic Heat Transfer and Skin Friction Drag Calculations written by Donald M. Wilson and published by . This book was released on 1967 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program is presented for calculating laminar and turbulent boundary layer heat transfer and skin friction drag on either a flat plate or a sharp cone during high-speed flight. Three turbulent skin friction laws, the Winkler-Cha, the Spalding-Chi and the Blasius-Sommer and Short are used so that comparative values can be found. The calculations are provided by a computer program which was written for an IBM 7090 computer operating under the IBSYS monitor. The mathematical formulations of the skin friction laws and the computer program are presented. Included with the program is a complete Fortran listing and all necessary instructions required for its use. (Author).
