Title: | Theoretical investigation of shock stand-off distance for non-equilibrium flows over spheres | Authors: | Shen, H Wen, CY |
Issue Date: | 2018 | Source: | Chinese journal of aeronautics, May 2018, v. 31, no. 5, p. 990-996 | Abstract: | We derived a theoretical solution of the shock stand-off distance for a non-equilibrium flow over spheres based on Wen and Hornung's solution and Olivier's solution. Compared with previous approaches, the main advantage of the present approach is allowing an analytic solution without involving any semi-empirical parameter for the whole non-equilibrium flow regimes. The effects of some important physical quantities therefore can be fully revealed via the analytic solution. By combining the current solution with Ideal Dissociating Gas (IDG) model, we investigate the effects of free stream kinetic energy and free stream dissociation level (which can be very different between different facilities) on the shock stand-off distance. | Keywords: | Gas dynamics Supersonic/hypersonic flow Shock stand-off distance Non-equilibrium flow Blunt body shock |
