混合有限分析法对加热Poiseuille流的数值模拟及分析

Numerical simulation and analysis of heated Poiseuille flow by hybrid finite analytic method

加热Poiseuille流是晶体生长控制技术中常见的一种流动,用混合有限分析法对之进行数值模拟,给出了流场的流线、涡量、压力和温度的等值线图;并给出了雷诺数和密度弗汝德数的倒数与产生漩涡的关系曲线.

The heated Poiseuille flow is very common in the region of crystal development control technique. The flow has been numerical simulated by hybrid finite analytic method (HFAM). The contours of the flow streamline, vortex, pressure and temperature have been obtained. The critical relation-curve between Reynolds number and the reciprocal of density Froude number for the vortex producing has been also given.
