舰载导弹垂直发射过程中甲板面燃气流场仿真分析

摘要

Based on the three-dimensional N-S equations and k-ε turbulent model,the influence of jet flow to the equipment on deck surface during shipborne missile vertical launching is emulation analyzed,using the numerical calculation method.By applying the numerical simulation,the pressure parameter distribution rule of jet flow field on the missile cabin cover,exhaust cover and deck surface are obtained during missile launching,and some characteristics curves are given,finally compare and verify with the reality test results.%基于三维、雷诺平均N-S方程和k-着二方程的紊流模型，采用数值计算方法对舰载导弹垂直发射过程中燃气流对甲板面及其上设备的影响进行了仿真分析。通过数值模拟，得到了导弹发射过程中产生的燃气流作用在弹舱盖、排气盖及甲板面上的压力分布规律，并给出了一些特性曲线，最后与实际试验结果进行了比较验证。
