The mathematical model of one-dimensional detonation flow in pulse engine was established on the basis of fluid mechanics theory.
运用流体力学的基本原理,建立了爆震流场的数学模型,确定了CE/SE方法的守恒元与求解元,对氢氧爆震波的形成和传播过程进行数值模拟,并将计算结果与逐次迭代法计算结果和实验值作了比较,验证了时空守恒元和解元方法计算一维非定爆震流场的有效性与高精度。
The present study aims on using oscillating flows and magn.
通过DNS方法解耦合的三维非稳态流动和固流体能量方程组,本文研究了两平行磁质平板和圆管所组成的肋片式圆管换热器单元与震荡流体间的传热过程。
