| Abstract: | One-dimensional flows originating during motion of a heat-conducting piston in a gas at high values of the Reynolds number are studied. The influence of diffusion and chemical reactions is considered in the case of a binary gas mixture. A binomial external expansion taking account of the boundary-layer-displacement thickness formed ahead of the piston is found. A solution is obtained which describes the boundary layer, which includes accommodation effects. An analogous problem about plane shock reflection from a heat-conducting wall has been considered in 1–3], but without taking account of diffusion and chemical reactions. Accomodation effects were taken into account in later work, which improved the agreement between theoretical and experimental results for short times. |
