摘要
针对潜艇集体逃生舱上浮过程的水动力问题,建立了典型集体逃生舱水下运动的数学模型,并重点对其释放后的上浮速度进行了数学仿真计算。然后,根据该流场的特点,合理选择求解条件,利用Fluent软件进行仿真分析。两种计算方法的结果吻合较好,结果表明:该集体逃生舱水下运动数学模型是正确的,其稳定上浮速度较大,在设计中应当进行控制。
In order to analyze the hydrodynamic performance of surfacing motion of submarine escape capsule, this paper establishes a typical mathematic model and conducts a conventional mathematic calculation of the ascent velocity variation after the submarine escape capsule is released. Then, a simu- lation study is carried out by use of Fluent to calculate the hydrodynamic performance variables. The results obtained from different calculations coincide show that the mathematic model of surfacing mo- tion is reasonable and that the ascent velocity of submarine escape capsule should be controlled in the design because higher ascent velocity is unfavorable to a submariner.
