声速喷管 meaning in English

sonic nozzle

Using axisymmetric full navier - stokes equations , the thermo - chemical nonequilibrium flow in hypersonic nozzle was simulated and the scale effects due to nonequilibrium were analysed numerically
摘要采用轴对称热化学非平衡全n - s方程，数值分析了高超声速喷管流场中非平衡引起的尺度效应。
The results show that to design a supersonic / hypersonic nozzle of wind tunnel must consider the effect of variable specific heat , which gives reference to nozzle and wind tunnel design
考虑这一因素后，喷管出口马赫数接近设计马赫数，其设计精度有较大提高。本方法可为超音速高超声速喷管设计和反设计提供参考。
