摘要
提出了一种直接边界元和离散旋涡法相结合的数值解析方法并对横流式风机的内部流动进行了计算，该方法不仅考虑了叶轮的作用，同时也考虑了涡室的影响。实测了横流式风机的内部流场并与计算结果作了比较，结果表明，该方法可望用于流体机械的性能预测。
A numerical analytic process is suggested combining direct boundary element methodwith discrete vortex method and internal flow in cross-flow fan is calculated.The processconsiders not only function of impeller,but also effect of volute casing. Internal flow field ofcross-flow fan is practically measured,and results are compared with that from calculation. It shows that the process is expected to be used in predicting performance of fluid machinery.
