摘要
介绍了汽轮机复杂结构部件内流场数值计算采用的计算方法、几何物理模型、参数的选取、边界条件的确定,并对排汽缸、汽封等的一些计算算例进行了简要介绍。
The method, the applicable geometrical and the physical model, the parameters to be chosen and the definition of the boundary conditions for numerical calculation of flow fields in complex steam turbine components is presented together with a brief introduction to some calculation examples like exhaust hood, and steam glands.
