Hello people, 

I am trying to simulate a model that has paraffin wax phase change material, how can i get the PCM proparties at different temperatures such as (Density, viscosity, specific heat capacity and thermal condutivity) if i want to perfom it as piece-wise linear on ansys fluent, is there any data source or should i contact the manufacturing company, although the technical datasheet provides only constant values ? 

Thanks in Advance

Hi,

You can refer to academic journal and research paper for the temperature dependent properties and can incorporate them in fluent using UDF, profile or piece wise linear.

Thank you.
