I mean if we want to get the thermal conductivity of PCM for a range of temperature i.e from solid to liquid phase, so can we get it by using a Thermal constant analyzer
For example: we want to get a trend of thermal conductivity for vaseline/ petroleum jelly from 20⁰C to 90⁰C.
Dear Muhammad,
if the required uncertainty of the planed measurement holds you may find some ideas in:
Determination of the Thermal Conductivity Based on a Thermal Capacitor Model

Hi Muhammad, you can use our (TA Instruments') FOX Heat Flow Meter instruments to test both thermal conductivity and specific heat of your PCM samples. See my papers here, at researchgate.net
I have used a Hot Disk Analyzer that allows you to make thermal conductivity measurements at different temperatures. The default model only permits measurements at room temperature. However, with the advanced models, you can get the thermal conductivity at different values of temperature.
