量项 meaning in English
quantifier
Examples
- The flux terms in the governing equations was directly calculated in the inertial coordinate system without projection to the rotate one
通量项计算直接在惯性坐标系下进行，没有投影到旋转坐标系下，方便了计算。 - The spatial flux terms are discretized by using central difference scheme and the time integration is performed by using explicit scheme in the flow solver
流场求解时采用中心差分的有限体积方法对空间通量项进行离散，采用显式推进方法进行时间方向的积分。 - ( 3 ) for parameterization of the sensible heat , the positively correlation between surface temperature and bulk transfer coefficient lead to a positive additional sub - scale flux . its magnitude is determined by the grid average roughness and average wind velocity on the reference level
( 3 )对区域感热通量的计算而言，由于地表温度和整体输送系数产生一个正的次网格通量项，它主要由网格平均粗糙度和参考高度平均风速所决定。 - The convective term is solved by ausm + ( a sequel to ausm which means " the advection upstream splitting method " ) . the 7 species 8 steps model and 7 species 7 steps model of hydrogen / air is used in the hydrogen reacting flowfield , the 9 species 5 steps model of methane , the 10 species 10 steps model of ethane and the 10 species 13 steps model of kerosene are used in the hydrocarbon reacting flowfield , the results of the distributions of velocity , mach number , pressure , static temperature , total temperature , species mass fraction and the combustion efficiency are gained , and the numerical results of the pressure of hydrogen and methane are compared with those of the experiment
计算中通量项采用ausm +通量分裂格式，氢反应流场采用氢/空气的七组元八方程模型和七组元七方程模型，碳氢反应流场采用甲烷的九组元五方程模型、乙烯的十组元十方程模型和煤油的十组元十三方程模型，得出了超燃发动机燃烧室流场的速度、马赫数、压力、静温、总温和组元质量分数分布及燃烧效率等性能参数，其中氢和甲烷的计算压力分布与实验结果进行了比较。
