Dear All,
I am a Trnsys 17 user, I want to model vertical storage tank containing coils as heat exchanger. My tank fluid is a phase change material that has temperature-dependent thermal properties ( specific heat, thermal conductivity, density and viscosity)
at this moment the closest type that could describe my case is the type 534-coiled from TESS library, the only thing is that this type only considers fixed thermal properties( not temperature dependent).
Does any one have an idea in how to model temperature dependence properties?
Many thanks
Best regards
