Where can I find the physical property formulas of terminols as in the picture I shared. Therminol 66, Therminol 62, Therminol VP-3, Therminol....(for all therminol heat transfer fluids)
Therminol is a standard thermal oil and the physical and chemical properties are published by the suppliers and are on the net: what are you looking for?
Berkan,
I used to operate a thermal conductivity laboratory.
The idea that any material, especially a fluid, has a thermal conductivity that can be measured with high repeatability to six decimals in W/m/K is laughable.
How well do you need to know these qualities?
To +- 1% (a typical industrial *good* measure)
To +-0.1% (an analytical *excellent* measure)
to +-0.01% (NIST and their ilk)
For example, a typical thermal conductivity rig relies on knowing the power needed to maintain a given temperature difference. And that's achieved by knowing the voltage across a heating resistor. A typical resistor might have a resistance uncertainty of +-0.1% - limiting the certainty on the thermal conductivity to the same factor.
For Therminol VP-3, I'd call it 0.117 W/m/K at rtp.

I strongly suspect that there are far greater uncertainties or simplifications in any model that you might be building.
As for a model? I'd look up the fluid being considered, and depending on the range of temperatures and the behaviour of the quality fit a model to the published data.
To obtain the physical property formulas for therminol, it is best to refer to the official technical documentation provided by the manufacturer.
For example, a manufacturer of Therminol is Eastman Chemical Company.
