Non-equilibrium dissociating nitrogen flow over spheres and circular cylinders
Theoretical results based on the methods of Freeman and Garr & Marrone show that the stand-off distance and flow pattern of non-equilibrium dissociating flow of nitrogen over the front part of a blunt body can be correlated in terms of a single reaction rate parameter s2 taking account of parameters describing the speed, density, dissociation and temperature of the free stream. The density patt...
متن کاملNon-equilibrium dissociating nitrogen flow over a wedge
Experimental results for dissociating nitrogen flow over a wedge, obtained in a free-piston shock tunnel, are described. Interferograms of the flow show clearly the curvature of the shock wave and the rise in fringe shift after the shock associated with the dissociation. It is shown that the shock curvature a t the tip of the wedge can be used to calculate the initial dissociation rate and that...
متن کاملExtension of a Multiscale Particle Scheme to Near-Equilibrium Viscous Flows
A recently proposed low-diffusion equilibrium particle method based on the direct simulation Monte Carlo method is modified for use with near-equilibrium viscous flows involving a simple gas. A finite volume discretization of the viscous terms in the compressible Navier–Stokes equations is used to incorporate diffusive transport effects into the low-diffusion particle method, and a velocity sli...
متن کاملDetailed Analysis of a Hybrid CFD-DSMC method for Hypersonic Non-Equilibrium Flows
A hybrid numerical scheme designed for hypersonic non-equilibrium flows is presented which solves the Navier-Stokes equations in regions of near-equilibrium and uses the direct simulation Monte Carlo method where the flow is in non-equilibrium. Detailed analysis of each stage of the hybrid cycle illustrates the difficulty in defining physically correct DSMC boundary conditions in regards to bot...
متن کاملnon-corrective approach to pronunciation
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
