Hello Dears, I want to perform heat transfer in PCMs simulation in COMSOL Multiphysics 5.0a in concentric tube heat exchanger. The hot water will be flowing in the central pipe while paraffin wax will be in the annulus. The longitudinal fins are also connected to the central pipe. I added two modules Laminar Flow and Heat Transfer in Fluids to the study. when i performed simulation it shows heat transfer in solids boundaries but not in the paraffin residing in the annulus. It does not show heat transfer due to hot water flowing in the central pipe. Anyone can help me how to couple laminar flow to heat transfer in paraffin? i.e. there will be heat transfer due to exhange of heat from hot flowing water in the central pipe to the paraffin in the annulus.
Thanks
