In order to improve the velocity of torpedoes, the transient calculation model of a torpedo launching propulsion pump during rapid start-up process was established based on the Reynolds average N-S equation and SST k-ω turbulence model in present paper. The hydraulic characteristics and the flow field evolution of the propulsion pump under three start-up time conditions were studied by numerical method. The results show that the flow rate and the thrust continue to increase with time. The head, the axial force, the axial moment and the power increase at first and then decrease. The efficiency firstly increases and then remains stable. The maximum values of the head, the axial force, the axial moment and the power appear at the end of acceleration, and the maximum values decrease with the increase of start-up time. At the beginning of start-up, there are serious inflow impact, flow separation and vortex structure in the impeller area, and the flow field tends to be stable gradually with time. Start-up time has a significant effect on the flow field evolution of the propulsion pump. The smaller the start-up time is, the faster the flow field reaches stable state. In order to ensure that the propulsion pump has no cavity and the internal flow field runs to stable state in a relatively short time during star-up process, it is recommended to start propulsion pump by 0.2 seconds start-up time.

为了提高鱼雷的出管速度,本文基于雷诺时均N-S方程和SST k-ω湍流模型建立鱼雷发射推进泵快速启动瞬态计算模型,采用数值方法研究三种启动时间条件下推进泵的水力特性及流场演变。研究结果表明:随着时间推移,流量和推力持续增加,扬程、轴向力、轴向力矩和功率先增大后减小,效率先增加后保持稳定。扬程、轴向力、轴向力矩和功率在加速结束瞬间存在极大值,且极大值随着启动时间的增大而减小。启动初期,叶轮区域存在严重的来流冲击、流动分离和漩涡结构,随着时间推移,流场逐渐趋于稳定;启动时间对推进泵流场演变具有显著影响,启动时间越小,流场越快达到稳定状态。为保证推进泵在启动过程中无空泡产生、内部流场以较快时间运行至稳定状态,建议以0.2 s启动时间启动推进泵。
