摘要
将 Witze的亚音速非稳定空气喷流模型进行密度修正、超音速喷射引起的气体膨胀的影响等修正之后 ,建立了描述超音速非稳定天然气喷流发展过程的基础方程式 ,计算了不同喷孔直径的天然气喷流速度、贯穿距离以及喷射角 ,探明了
With correction of Witze's calculating model for the effects of the jet density and the supersonic jet expanded outside the nozzle,equations for simultaneous estimation of the supersonic and transient natural gas jet characteristics have been developed in the paper.Moreover the velocity penetration and spray angle of jet were calculated in various nozzle radius.The transient natural gas jet extending process used in MPI system was also revealed.
