3D Simulation of Velocity Field for Polymeric Fluids in a Closed Channel With the Finite Volume Method (FVM)

In this research the velocity field of a typical polymeric fluid is simulated in a closed channel with the finite volume method (FVM). The simulation was three dimensional and discretization performed using central difference method. For optimizing of the simulation, an under relaxation factor (URF) was considered. It was found that by using URF equal to 0.5, simulation has more rapid convergence. Also considering lower Reynolds number has led to shorter fully developing length. Power law index (n) also had a same effect
