Numerical simulation of power-law inelastic fluid in channal by using finite element method

الملخص EN

In this paper the numerical study for incompressible power-low inelastic fluid is presented.

Physically, a continuity equation (mass conservation) and time-dependent conservation of momentum equations are utilized to describe the motion of the fluid.

Moreover, the flow problem is solved under viscous inelastic assumptions, with a power-law inelastic model (????).

Numerically, the study has been conducted based on the Galerkin finite element method (????).

Attention is paid to the comparison between Newtonian results and shear-thinning inelastic.

The analysis of convergence under the parameters of power-low inelastic model and Reynolds number is conducted.

The Findings reveal that, there is a significant effect from the inelastic parameters upon the the velocity temporal convergence-rates of velocity, while for pressue, the change in convergence is modest.
