Analysis of Rarefied Nozzle Flow by Generalized Hydrodynamic Equations

GH 방정식을 이용한 희박 노즐의 해석

This paper presents the analysis of flowfield inside a low-density nozzle and its plume into near vacuum. The generalized hydrodynamics equations are numerically solved for the purpose with the help of modern computational fluid dynamic methods. The results taken along the nozzle are compared with those of Navier-Stokes equations and available experimental data. The plume outside the nozzle is also analyzed in order to examine the adverse effects of its impingements.
