| 摘 要： | 液体火箭发动机喷雾液滴在表面剪切力的作用下形成内部环流,影响液滴内部传热特性,进而影响喷雾蒸发燃烧过程.将一种基于光滑压力修正的非交错网格sIMPLE算法推广到一般曲线坐标系,并对液滴表面特殊边界条件进行数值处理,然后采用代数法生成正交贴体结构网格,求解气相及液相轴对称不可压流动控制方程,得到运动液滴内部稳态流场及其温...

| Abstract: | Internal recirculation is formed in the liquid rocket spray droplet because of the surface tangent stress,which would influence the internal heat transfer of droplet greatly,and then the spray evaporation and combustion procedure.A smoothing pressure correction non-staggered SIMPLE algorithm is introduced into the curvilinear coordinates along with numerically processing for the special boundary condition of droplet surface,and then the axi-ymmetrical incompressible flow control equations of the gas and liq... |
