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。
This paper presents a TG finite element method to analyze mass, momentum and energy transfer problems. This method retains the third-order accuracy of space and implies the dissipative effect of the flow-line upwind. It can be used well in the flow of high Reynolds and Peclect numbers, and the pressure correction method is adopted to adapt the calculation format to compressible Fluid and incompressible fluid. In order to adapt to the existing computing conditions, memory and speed are balanced selection, the corresponding algorithms and storage methods are proposed. Finally, the calculation results of 2-D and 3-D branch flow fields are given.
