摘要
结合一个轴流项目专题着重研究了蜗壳 ,通过求解平均化 Navier-Stokes方程 ,数值分析不完全蜗壳内的流动 ,并依分析结果对蜗壳进行重新设计。在其它通流部件不变的情况下 ,试验比较了新旧蜗壳下的机组的水力性能参数。图 1 2表 1参
In present research, we studied a semi spiral in a special topic by flow simulation with solving the averaged Navler Stokes equation. According to numerical analysis result, We redesigned a new spiral casing. Keeping the same other flow passage, we compared their hydraulic performance of the whole machine by model test with different spiral. Figs 12, tablel and refs 3.
