fluid dynamics - How to calculate Shear Rate magnitude for Compressible Flow?


I'd like to calculate the shear rate formula for CFD (Non-newtonian Fluid) and want to know if the following formula is the good one:


Viscious Stress General Equation (Tensor): Viscious Stress General Equation (Tensor)


So the magnitude of the shear rate is: So the magnitude of the shear rate is:


Is this shear rate magnitude formula correct?


Thanks
