喷管出口马赫数 meaning in Chinese
nozzle exit mach number
Examples
- 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。 - To prove the accuracy of the mach number , and the parameter homogeneity of the design nozzle " s exit , cfd calculate has carried on the design results . under the condition of supersonic and hypersonic flow , and a certain range of temperature , and mach number , the conclusion of the influence of specific heat to nozzle design is drawn
为了验证所设计的喷管出口马赫数的大小和喷管出口流场的均匀性，采用nnd格式和b l湍流模型求解雷诺平均n - s方程，对设计结果进行了cfd验算，得出了在一定温度范围内，超音速、高超声速流动的条件下，不同马赫数范围内变比热容对喷管型面和喷管出口马赫数的影响。 - Then , the one dimensional model is used to study on some factors ( viscosity , the heat given out by the chemical reaction in the chemical laser ) which bring the loss of the total pressure . the answer shows that increasing the mach number at out of the nozzles in the laser can reduce the loss of the total pressure
在此基础上,用简化的一维模型研究了引起激光器总压损失的几个要素,它们是:喷管的粘性损失,光腔内的放热化学反应。研究的结果表明,提高喷管出口马赫数有利于减少这些因素导致的总压损失。
