chopsu is on a distinguished road
Hello everyone,

Im working on some multiphase simulations which involve liq-air and in which the liquid viscosity is strongly dependent of shear rate. I have experimental data about the evolution of viscosity due to shear rate and I would like to implement on Fluent. I saw it would fit well with the Carreu Model, but i have so much data I would use and UDF to interpolate it.

My question is about the cost of each method, I currently don't have a very powerful machine so, which would be the cheaper method?

Thanks all
