Abstract : In this work a new, two-fluid model for the hypervelocity rarefied regime is presented. To obtain expressions for the absorption and emission terms in the model, the distribution function of each fluid is represented by an expansion in the derivatives of the delta function and the relevant intergrations are performed. Equations are analyzed for the case of one-dimensional hypersonic compression (piston problem), and numerical results are presented. The velocity and density profiles are shown as functions of time and distance from the plate, and the speed ratio of the cold fluid is plotted. (Author)
