超音速射流 meaning in Chinese
supersonic departure
supersonic jet
Examples
- In this way , supersonic fluid amplifier especially bistable valve with negative pressure switch is used in the rocket projectile thanks to its advantages of switching rapidly , the ability of low temperature air to control the high temperature gas and no moving parts in high temperature gas
超音速射流双稳阀，特别是采用负压切换的超音速射流双稳阀因其具有切换快速、可用低温气流控制高温燃气和在高温燃气中无活动部件的优点而适用于火箭弹的姿态控制系统中。 - In some applications , for example in rocket engine , the simulation full three - dimensional model is necessary . finally , we explain the phenomenon in the experiment with the results of simulation and verify the dependability and accuracy of this numerical simulation through the co mparison with the experimental data
本文利用三维流场的计算结果合理地解释了实验中发生的现象，并通过与已有的实验数据的对比，验证了超音速射流双稳阀数值模拟的可靠性和准确性，有望应用于实际工程的初步设计。 - And then , in the simulation of three - dimensional , the application of o - type grid and hybrid grid are used in two relatively complicated structures make the total amounts of grids and the time of grid generation reduced greatly . moreover the hexahedron grids are placed in most areas to provide higher precision . through the comparison between the results of two - dimensional and three - dimensional simulation , we knew two - dimensional calculating is not adequate
本文用简单、方便的二维模型作为数值计算的起点，使用耦合隐式算法以及先进的v2f湍流模型进行求解，成功地捕捉到了激波，观察到主气流从壁面的分离、切换、再附壁等现象，并对计算结果进行了细致的分析，得出一些有意义的结论；在此基础上，本文在国内外首次对超音速射流双稳阀的三维流场进行了计算。 - This article briefly explains the basic principle of coherent jet technology , and contrasts the characteristics of coherent jet with supersonic jet , accordingly the coherent jet technology has lower decay , longer jet distance and less absence of dimple etc , to form into a greater depth of penetration for any stand - off distance and ameliorate the effect of mixing round for liquid
