| Abstract: | The investigation of the upstream-downstream intermittent reversing flow in the near wall of a 2-D channel is attempted with a 2-D laser doppler velocimeter (LDV). The effective measuring height nearest to the wall is 0.3mm. The experimental results are presented, and the influences on the LDV near-wall measurement are discussed. |
