A Numerical Analysis of CO2 Laser Radiation Absorption in SF6-Air Laminar Boundary Layers,

Abstract

Numerical results are presented for the radiative gasdynamic interaction associated with CO2 laser radiation absorption in SF6-air laminar compressible boundary layers. Detailed boundary layer profiles and the variation of radiative intensity are obtained for the sonic flow over a flat plate at sea level, wherein SF6 is injected into the boundary layer through the surface, and CO2 laser radiation at 10.6 micrometers is incident on the plate downstream of the injection. The numerical solution of the non-similar boundary layer equations employs a difference-differential technique. (Modified author abstract)
