Hi folks,

I am studying the heat transfer on fouled piping and I need somehow to include a model relating fouling (deposit thickness) to time, and thermal conductivity to thickness.
I have retrieved experimental data for deposit growth (thickness vs time) and thermal conductivity (thermal conductivity to thickness), and although I could just lump them into one function relating thermal conductivity to time, I was wondering if the Thickness parameter in Fluent could be a variable of time.

Thanks for your help.

I think you have to alter the thermal conductivity [w/mK] with udf as you said.
