| Abstract: | This paper presents a fundamental gaskinetic study on high speed rarefied jets expanding into vacuum from a cluster of planar exits. Based on the corresponding exact expressions for one planar jet, this paper straightforwardly derives the combined multiple jet flowfield solutions of density and velocity components, however, for the combined temperature and pressure solutions, extra attention shall be practiced. Several direct simulation Monte Carlo simulation results are provided and they validate these analytical solutions of rarefied planar jet flows. |
