The purpose of our study is to visualize the velocity field around swimmer's hand and to analyze the vorticity generated by hand using PIV. Experiments were carried out in a swimming flume. YAG laser sheet was used to illuminate the tracer particles around the swimmer's hand. The images were captured by a CCD camera and stored in a personal computer. We made the image, vector and vorticity maps using MATLAB. We investigated the four top swimmer's qualitative characteristics of the distributions of vorticity and velocity vectors using 2CPIV. 3CPIV system was developed to see the three dimensional structure of vortices. We succeeded the flow visualization around swimmer's hand using this system, clarified the unsteady three dimensional flow fields, and evaluated the force generated by the hand qualitatively.
