Combined technique of Particle Imaging Velocimetry (PIV) in conjunction with Computational Fluid Dynamics (CFD) makes it possible to predict detailed fluid flow structures. Turbulent flow containing fine solid particles in a channel is one of typical examples which are not solved only by PIV nor by CFD. In this study, the solid particle behavior in a converging channel is predicted by theoretical equations after the carrier phase flow field is measured by PIV. The results have shown the dependency of the particle behavior on its force components, such as inertia and lift forces.
