Abstract

Viscosity of the shear-thinning fluid depends on the shear rate. This study is conducted in Taylor vortex flow conditioned by the rotation of inner cylinder and stillness of outer cylinder and just taking into account the axial flow for estimating the parameters of flow (velocity and pressure components) in the narrow gap between two cylinders. The results of this study are important in the bearing application. The equations of Taylor-Couette flow and Galerkin method were obtained by the equations for the conservation of mass and momentum equations. Flow parameters were obtained by Fortran and investigated by Mathematica software. The flow is the sum of base flow and a deviation from the base flow. According to the main results of analysis above, the target diagrams are compared with Newtonian and a diagrams. The more the value of parameter a is reduced, the quicker the flow will become critical. All components of real velocity and pressure are reduced while increasing Shear-thinning.
