Title: Momentum equations for Non-newtonian fluid?
Post by: Engineer in making on November 30, 2014, 05:51:06 PM

Hi everyone,
 
I'm trying to solve a fluid problem for isothermal, steady, unidirectional laminar flow of an incompressible non-Newtonian. And was asked to solve the navier stokes equation ( Momentum equation) for it. Here's the diagram:

Shear stress formula :

Mementum equation:

My solution:

I'm just wondering If my approach for the problem and my solution was right since I'm having doubts about my solution.

That's not a solution. A solution would give you u_x as a function of y.
