fan out grating

The tip leakage flow and its effect on heat transfer in the tip gap of a sectorial turbine cascade is discussed.

本文通过在水槽中用粒子示踪的方法，利用最新的ＰＩＶ技术对扇形叶栅叶尖间隙泄漏流进行了定量流动显示。

A new θmodulating technique without encoded grating and a useful method for recording fanout grating are proposed, and the experimental results are also given.
