Abstract
One camera and multi-layer laser sheet PIV technique has been studied in our lab. But its method couldn't measure the 3-dimensional reverse flow against the camera.
In this paper, a new technique is proposed to measure the 3-dimensional flow which contain the reverse flow by moving multi-laser sheet method.
Uniform tow fields are measured to calibrate this method. The wake flow of the model-scale ship is measured. It is compared the velocity distribution with previous 5-hole pitot probe data and previous method in our lab. Better agreement is obtained than previous method. Cavity Flow field is also measured to confirm and compared with LDV measurement in 3-dimensional flow. Good agreement is obtained between them.
