摘要
针对汽轮机超临界级变工况计算过程中存在的马赫数M >1与M <1交替发生而使计算不收敛的问题 ,分析了其产生的原因 。
Aiming at the questions that the Mach number M>1 and M<1 happens alternately in calculating supercritical velocity steam turbine stages at off-design condition and that causes the calculation not converging, the reasons are analyzed, and the improved calculating method is given.
