mach number

The hot air permitted higher speeds before the critical Mach number was exceeded

热空气可使之在超过临界马赫数之前达到更快的速度。

Aimed at the jet noise which is induced by the expand structure and tail tube in the resistant muffler, a finite element model at low Mach number was developed.

针对抗性消声器中扩张结构和尾管引起的射流噪声问题，建立了低马赫数射流噪声有限元分析模型。

Under the high-speed airflow disturbance condition, the combustion time of the igniter declined when the Mach number increased, the combustion was fierce, and the flame length was several times longer then that under the static state.

在高速气流扰动条件下，点火具燃烧时间随马赫数增大而减小，点火具燃烧猛烈，火焰被拉长数倍。

The hot air permitted higher speeds before the critical Mach number was exceeded.

热空气可使之在超过临界马赫数之前达到更快的速度。

There are shock lets in the mixing layer with convective Mach number 1.2.

高对流马赫数混合层中存在较弱的小激波间断.

It can insulate the upstream and downstream flow field resulting in the noise drop of the text section from the downstream and can control the Mach number exactly in the transonic state.

它在跨声速状态下具有隔离上下游流场从而降低试验段噪声，精确控制马赫数的作用。

The profiles of density, velocity, temperature, pressure and Mach number can be obtained by the computation.

通过计算可以得出密度 、 速度 、 温度 、 压力和马赫数的分布.

A code is developed to predict the Mach number compressible fluid flow with pressure-correction algorithm . 2 .

开发了适用于低马赫数流动的可压缩压力修正算法程序.
