Varying Reynolds number in powerLaw model?
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. |
