摘要：
A new method of measuring a three dimensional unsteady flow is presented. The method was applied to the measurement of a flow just before the impeller of a centrifugal fan operating in the state of rotating stall, and complex flow patterns in that place were made clear. The method described is very useful to elucidate the complex flow in turbo-machines which operate in an unstable state and the flow which varies its direction over a wide range periodically.
