Stress Analysis of Mixing of Non-Newtonian Flows in
Cylindrical Vessel Induced by Co-Rotating Stirrers Keywords: Mixing Flows, Non-Newtonian Fluids, Rotational Flow, Co-Rotating Stirrers Mehran University Research Journal of Engineering & Technology Volume 32 , Issue 2 RAFIQUE AHMED MEMON,MUHAMMAD ANWAR SOLANGI,AHSANULLAH BALOCH Abstract The impacts of rotational velocity and inertia on velocity gradients and stresses are addressed under present study. The non-Newtonian behaviour of inelastic rotating flows is predicted by employing Power law model. A numerical model has been developed for mixing flow within a cylindrical vessel along a couple of stirrers. A time marching FEM (Finite Element Method) is employed to predict the required solution. Predicted solutions are presented for minimum to maximum values in terms of contour plots of velocity gradients and shear stresses, over the range. The long term application of this research will be used to improve the design of mixers and processing products. The predicted results are used to generate the capability and are in good agreement with numerical results to the mixer design that will ultimately effect the processing of dough products |
