Abstract: A new algorithm for automatically detecting spurious vectors in PIV data is set up by using Delauney tessellation technique and considering continuity of fluid. The method is justified by simulating a solid rotational flow. The results show that the method can identify the spurious vectors precisely. In addition, the deleted points can be interpolated by the Delauney tessellation technique and the full-field velocity vectors can be obtained. Finally, the new method is applied to the real experimental images.
