Dear all,

I was wondering if it's possible to simulate phase change (melting) with Icepak. I want to simulate a PCM (phase change material), I could not find it in the help.

Any information is highly appreciated.

Thanks you

Hi.. It's not possible to simulate phase change in Icepak.
Irrespective of it's a gap pad / phase change material / Thermal paste, we can only assign thermal conductivity/ resistance or thermal impedance. If any characteristics to be observed, you can do it using any available characteristics curve and final operating temperature..

Where can I find the viscosity value for PCMs produced by RUBITHERM company such as RT28HC and SP29Eu which is not available in their data sheet?

Hello my Dear friend rzyz,
If you still have not found your answer to the question, here it is,

viscosity(T)=0.001*exp(-4.25+(1790/T)), the value "0.001" is because of introduce the formula in SI (mass in Kg unit).

This formula is true when material is in liquid phase. The reference to access is:
