摘要
本文提出了一种分析质量、动量和能量传输问题的TG有限元法。该法保留了空间的3阶精度,隐含了流线迎风的耗散作用,可很好地用于高Reynolds和高Peclect数的流动中,采用了压力修正法,使计算格式同时适应可压缩流体和不可压缩流体。为了适应现有计算条件,将内存和速度进行了均衡选择,提出了相应的算法和贮存方式。最后给出了2维、3维分支流场的计算结果。
In this paper, the TG element method for analysis of the transfer of mass. momentum andenergy is proposed. This method maintains three order space accuracy and implies stremline-upwinding dissipation mechanism, which can be used to overcome the difficulty of convective unstability for high Reynolds number flow. The pressure correction method is adopted, so that both incompressible and compressible flow can be treated. Based on current computing condition, the balance between memory and speed is made and accordingly algrithm and storage format are provided. At last, the caculated results of two dimensional and three dimensional branch junction flowfield are presented.
