3D Simulation of Velocity Field for Polymeric Fluids in Rotational Cylinder Rheometer with the Finite Volume Method (FVM)

In this research the velocity field of polymeric fluids is simulated in rotational cylinder rheometer with the finite volume method (FVM). The simulation was three dimensional and the discretization performed using central difference method. For optimizing of the simulation, an Under Relaxation Factor (URF) parameter was considered. It was found that by using URF equal to 0.7, simulation has more rapid convergence. Considering lower power law index (n) also had a similar effect
