利用计算流体力学的仿真软件FLUENT对鱼雷发射箱在使用扇形孔导流隔板和无导流隔板两个工况下的内流场变化情况进行仿真计算,通过仿真计算分析导流隔板对发射箱内流场的影响。仿真和优化结果表明,与无导流隔板工况相比,此导流隔板能使后盖受到更加均匀的压强作用,且后盖可正常碎裂,但前盖受压效果不理想,需要进一步改善;优化后该方案能够使前后盖按设计目标破碎。
Using the computational fluid dynamics simulation software FLUENT, the flow field of the torpedo launching box under the two conditions of fan-shaped and non-flow-conducting baffles was simulated and calculated. Effect of the flow field inside the launch box. The results of simulation and optimization show that the deflector can make the back cover more uniform pressure than the non-deflector, and the back cover can be cracked normally. However, the pressure effect of the front cover is not satisfactory, Need to be further improved; after optimization, the program can make the front and rear covers broken according to the design goal.
