dyn. viscosity as a function of particle Temp.

July 6, 2006, 11:48

Hi all,

I would like to create a dyn. viscosity of my liquid particles as a function of the particle temperature. Has anybody experience with this? I am using CFX 10.0 and a lagrangian particle model. Is it possible to solve this problem without using fortran subroutines? If yes how can I find out the variablename of the particle Temperature?

Cheers, Felix

hi just explain ur problem clearly what ur simulating exactly

I am simulating the motion of liquid and inert particles with a diameter of 0.1 micron in a gas flow. You can define a value for the dyn. viscosity in the "material properties" -> "Transport properties" settings. And I want to create a function for this dyn. viscosity which depends on the particle temperature. The background of my question is that I would like to associate the perpendicular/parallel coefficient with that dyn. viscosity to obtain a behaviour for the stickiness of the particles. Do you need more information?
