Hi everyone,
I am struggling to setup a non-newtonian fluid within multiphaseInterFoam. It was straightforward before Openfoam 10 was released, were it was setup within transportProperties. This new method where the non-newtonian model is setup within momentum transport is too confusing. Can someone please help me figure it out. I found a tutorial implementing a non-newtonian fluid within pimpleFoam. But that also makes no sense as the viscosity model is set to "constant" Here is what I have, it managed to run but I am not sure if the crossPowerLaw is applied. MomentumTransport: Code:
simulationType laminar; laminar { model generalisedNewtonian; viscosityModel CrossPowerLaw; CrossPowerLawCoeffs { nu0 [0 2 -1 0 0 0 0] 1-05; nuInf [0 2 -1 0 0 0 0] 1E-12; m [0 0 1 0 0 0 0] 1.00E-03; n [0 0 0 0 0 0 0] 0.7; } } Code:
viscosityModel constant; rho 1000; m 1.00E-03; n 0.7; nu 1E-05; nuInf 1E-12; Code:
PIMPLE: Operating solver in transient mode with 6 outer correctors Reading field p_rgh Reading field U Reading/calculating face flux field phi Selecting viscosity model Newtonian Selecting viscosity model Newtonian Selecting viscosity model constant Selecting turbulence model type laminar Selecting laminar stress model generalisedNewtonian Selecting generalised Newtonian model CrossPowerLaw Reading g Reading hRef Calculating field g.h No MRF models present No fvModels present No fvConstraints present |
