摘要
为了详细、直观、准确地描述发射过程中空气涡轮泵发射装置在假海试验设施内部流场的压力场、速度场分布,建立了在发射试验过程中假海试验设施内流场的数学模型,并运用Fluent的动网格技术对该模型进行了数值仿真。仿真结果显示了假海试验过程中各个阶段的压力场和速度场的分布情况,为试验设计提供参考。依照仿真结果对试验过程中出现的一些现象做出解释。根据假海内部流场的仿真结果对流场的恢复情况进行预测,为连续发射时间间隔的确定提供理论依据。
To obtain a detailed, intuitive and accurate description of the pressure field and velocity field distribution of inner flow field in false sea test facility for an air-turbine pump launcher during launching, a mathematical model of inner flow field in false sea test facility is established, and simulation is conducted by using dynamic mesh of FLUENT. The results illustrate the distributions of pressure field and velocity field of inner flow field in false sea test facility at every stage of the launching process, which may be taken as a reference for test design. In addition, explanation is given for the phenomena appeared during the launching test by considering the simulation results of false sea test. And the recovery state of the inner flow field is predicted according to the simulation results to provide a theoretical basis for determining time interval between two continuous launching.
