Figure 4- History of (a) velocity, (b) position (c) rotation parameters for an elliptical particle with \(D_{p}=(2.0,0.5)\) and \(\frac{\rho_{p}}{\rho_{f}=10}\) at\(\ Fr=0.51\). The particle collides with a frictionless wall. The top and bottom figures show the results for \(Re=20\ \)and \(Re=2000\) respectively. \(T=0\) is the time that the particle starts the course of collision and is free to rotate.
