摘要
本文发展了一种具有TVD性质的三阶精度的Godunov格式。隐式部分采用迎风对角线形隐式近似因式分解法。并引入了粘性通量的简化算法。显式部分采用三阶精度TVD格式。为进一步增强格式的稳定性及对间断的捕捉能力，在单元边界上构造Riemann问题。应用上述方法对某型涡轮高压级及压气机进行了数值模拟。
This paper developed a third order Godunov scheme with TVD property. Up wind AF method and viscous flux simplification are employed in implicit operator while third order TVD scheme is used in explicit operator. Riemann problem is constructed on cell boundary to enhance the stability and discontinuity capture ability. Application of this numerical method to multistage turbine and compressor rotator are also presented.
