Zeitoun Física, Astronomía y Matemáticas Hypersonic flows past Brazilian satellite SARA at zero angle of attack in chemical and thermal nonequilibriumare investigated using an axisymmetric Navier-Stokes solver. The numerical solutions were carried outfor freestream conditions equivalent to a typically re-entry trajectory with a range of Mach numbers from 10to 25. The gas was chemically composed by seven air species O;N;NO;O2, N2;NO+; e¡ with 24 stepschemical reactions scheme and thermically characterized by a multi-temperature model. Comparisons havebeen made between the present computation and the distribution of pressure coefficient and the heat transferobtained recently with Direct Simulation Monte Carlo Method[1]. The study also points out the influence ofnonequilibrium phenomena like ionization, vibrational and electronic excitation on aerothermodynamic flowparameters. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435110 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1 Vol.35 |
