STRONG VISCOUS INTERACTION WITH MASS TRANSFER IN AXISYMMETRIC HYPERSONIC FLOW.
Abstract
A theory is presented for the combined effects of mass transfer and viscous interaction on the hypersonic flow of a perfect gas in the limit where the body is vanishingly thin compared with an adjacent, single-species laminar boundary layer. The body temperature and a mass transfer parameter F must both be constant, but arbitrary body profiles are allowed. The results are applicable to porous bodies with nearly uniform mass transfer per unit length and to ablative bodies with a constant effective heat of ablation. The major boundary-layer properties are presented as analytic functions of Prandtl number, specific heat ratio, power-law viscosity power, body enthalpy ratio, and mass-transfer parameter. The theory is compared with numerical solutions for a thin body which grows as a three-quarter power law, and it is found to accurately predict the relative effects of mass transfer. (Author)
