摘要

摘要: 针对水冲压发动机燃烧过程中不同喷水位置和喷水量两种主要影响因素,以金属/水冲压发动机为物理模型,以N-S方程为数学模型,以数值模拟方法为研究手段,湍流采用重整化的k-ε湍流模型,燃烧采用Eddy-Dissipation模型,模拟了不同条件下补燃室内燃烧两相湍流流动,以燃烧效率为评价准则计算了不同条件下补燃室燃烧效率,得到了优化的二次进水位置和一次进水分配比。

Abstract: By using the numerical simulation method,the paper study two major effect factors-water spray location and quantity-on the combustion process of water ramjet. The physical,mathematical,turbulent,combustion models are metal /water ramjet,N-S equations,realizable k-ε and Eddy-dissipation,respectively. Through simulating the afterburning chamber under different conditions and using combustion rate as evaluation criteria,the paper gets an optimization secondary water spray location and distribution ratio of the first water inlet,which provides theoretical references for water ramjet design.
