Study on Estimation Method of Flow Fields by PIV Combined with CFD

It is difficult to grasp the whole flow field accurately by PIV, because the velocity vector is located at a wall surface is missing in most cases. In this study, therefore, we examine an interpolation method by making use of the advantage of PIV and CFD.In this paper, two-dimensional cavity flow is also treated as an example of the application. We also devise how to make the velocity vector diagram using the pressure information at the location where the velocity vector is absence.
