Hi there,

I am simulating the flow of power law fluids through the sudden expansion plane of a regular diverging nozzle. With the newtonian model it allows you to set the value simply using nu [ 0 2 -1 0 0 0 0 ] however my transport properties file for the power law model is as follows;

powerLawCoeffs
{
k k [ 0 2 -1 0 0 0 0 ] 894;
n n [ 0 0 0 0 0 0 0 ] 0.8;
nuMin nuMin [ 0 2 -1 0 0 0 0 ] 1e-06;
nuMax nuMax [ 0 2 -1 0 0 0 0 ] 1e+07;
}


Ive read elsewhere that these are the right dimension for K contrary to the maths.

I have the RAS model as laminar with turbulence off, though im not sure this is right If I would like to vary the Reynolds number also?

Any help appreciated I am new to this software,

Thanks.
