水反应金属燃料发动机三维内流场数值模拟
Numerical simulation of the 3-Dimesional internal flow field of a hydro-reactive metal fuel motor
摘要
Abstract
Hydro-reactive metal fuel motors have recently attracted significant attention. A magnesium/water reaction model and aluminum/water reaction model which considered alumina smoke accumulation were developed. A full heat release model for metal/water burning mechanisms was also used to simulate the 3-dimesional internal flow field of the motor. The movement laws of different types of droplets in the combustion chamber were researched. Results obtained from the computations show that with the regular motor format,compared to the magnesium/water system,there were more solid droplets in the motor of the aluminum/water system after burning,and that the entire flow field was full of aluminum droplets,while the magnesium droplets burned more rapidly and completely. However,there is no remarkable difference in the evaporation efficiency of water droplets between these two systems. The computation results coincide with the relative experiment phenomenon.关键词
