Connie was half listening , and threading in the hair at the root of his belly a few forget - me - nots that she had gathered on the way to the hut . outside , the world had gone still , and a little icy 康妮半听着,一边把她到小屋里来时在路上所采的几朵毋忘我,结在他小腹下的毛丛里,外面已变成静温而有点寒冷了。
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。
