利用建立的再生式液体药火炮（ＲＬＰＧ）中再生喷射燃烧过程的多维多相流数学模型，以３７ｍｍＲＬＰＧ为对象，对其再生喷射燃烧过程进行了全模拟，揭示了过程中各物理量的时空分布特征。结果表明：（１）整个液体喷射过程期间，燃烧室内存在连续的液注形态。液体药的燃烧主要发生在燃烧室和身管入口区域。（２）身管入口节流对燃气流速和压力的时空分布产生重要影响。身管中段的燃气流速和压力沿轴向成线性分布。（３）燃烧室和身管入口附近区域处于同一高温水平，相应区域的壁面热负荷较大。身管内燃气温度沿弹底方向逐渐降低。
Based on the multi-dimensional multiphase flow mathematical model of regenerative injection liquid propellants (RLPGs), the 37mm RLPG was used to simulate the combustion process of regenerative injection and reveal the spatiotemporal distribution of each physical quantity in the process . The results show that: (1) There is continuous liquid injection in the combustion chamber during the entire liquid injection process. The burning of liquid medicine occurs mainly in the combustion chamber and the entrance to the barrel. (2) Throttle inlet throttle has an important impact on the spatial and temporal distribution of gas velocity and pressure. Gas flow velocity and pressure in the middle of the barrel are linearly distributed in the axial direction. (3) The area near the combustion chamber and the entrance of the barrel is at the same high temperature level, and the thermal load on the wall in the corresponding area is larger. The temperature of the gas in the barrel gradually decreases along the direction of the bottom of the bomb.
