摘　　要：讨论了斜式进水流道流场可视化与模拟的过程及实现环境,基于CFD计算结果的网格图形显示方式,分析了斜式进水流道多断面流场可视化的表达及色彩处理问题.在AutoCAD环境下,利用ObjectARX开发平台较好地实现了斜式进水流道多断面流场的三维显示、基于流线表达方式的流场整体可视化及基于计算机图形学中经典算法的实时流场的模拟.采用OpenGL色彩处理功能展示了多断面流场的特性.结果表明,流场可视化可直观形象地展示斜式进水流道内流场的分布,检验其数值模拟计算的流场特性,便于工程技术人员对数值模拟计算结果的理解,为进一步优化计算流场提供依据.The realization of visualization of flow fields and the process of numerical simulation were introduced. Based on the display mode of the CFD simulation results, the realization platform of visualiza- tion and simulation for inclined inlet passage of pump stations was analyzed. In the Autocad environment, on the ObjectARX exploitation platform, the three dimensional display for multi-section flow field in the inclined inlet flow passage, the whole flow field visualization which based on streamline expression mode, and the flow field real time simulation based on the figure apoplexy involving the channels allusion algorithmic were realized. And the characteristics of flow field for many section of inclined inlet passage are also presented with OpenGL color functions. The results show that, flow visualization can show the distri- bution of the inclined type inlet flow passage directly, verify the numerical simulation results, facilitate the understanding of the computational results, and provide many informations for the optimizations of flow field.
