This book was released on 1967 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented for several numerical experiments using an analysis of the viscous radiating stagnation region shock layer and stagnation point heat transfer. A simple step model absorption coefficient, rationally constructed from existing quantum mechanical calculations, is shown to accurately predict shock layer nongray continuum radiative heat transfer in comparison to results obtained with detailed spectral absorption coefficients. Sensitivity of the heat transfer to uncertainties in gas radiative and transport properties is also examined, as well as the effect of artificially increased absorption in the boundary layer.

Download or read book An Equation for Rapid Calculation of Stagnation Point Radiative Heat Transfer written by John David Anderson (Jr.) and published by . This book was released on 1968 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A closed-form equation is derived for stagnation point reentry radiative heat transfer accounting for the combined effects of radiative cooling and nongray self-absorption within the shock layer. The equation can be applied for both continuum and atomic line radiation. In addition, the equation is shown to agree favorably with existing numerical data for stagnation point, continuum radiative heat transfer for a wide variety of conditions. Also, the equation is shown to apply to the end-wall radiative heat transfer behind a strong reflected shock wave in a shock tube. Finally, the equation provides a rapid means of obtaining, by hand, reasonably accurate engineering estimates for reentry radiative heat transfer including shock layer radiative cooling and nongray self-absorption.

This book was released on 1969 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A second-order time-asymptotic solution to radiation-coupled stagnation-region flows is presented. The solution is applied to the hypervelocity flow over blunt vehicles of inviscid, nonconducting, equilibrium air, emitting and absorbing nongray radiation. Velocities, nose radii, and altitudes covered by the analysis are sufficient to bracket reentry trajectories of current interest. Radiative heat-transfer rates for the range of interest and typical profiles of pressure, density, enthalpy, temperature, and velocity are shown. The nature of time-asymptotic solution is discussed and it is shown o be a feasible means of achieving second-order accurate solutions to radiation-coupled shock-layer flows. Step-function models of the absorption coefficient are used in order to evaluate the divergence of the radiation flux vector. An analysis is carried out to determine what effect variations in the spectral complexity of the step model absorption coefficients used in the analysis will have on the thermodynamic and flow profiles of interest and on the nongray radiative heat-transfer rates. In this connection use is made of consistent model absorption coefficients having one to nine spectral steps with free-free, free-bound (including atomic line transitions), and molecular transitions taken into account. Relatively simple models of the absorption coefficient can be used with no significant loss of accuracy. An existing correlation for the cooling factor, the ratio of the radiation heat-transfer rate to the adiabatic radiation heat-transfer rate, is extended to larger velocities than heretofore considered.
