Heat transfer between fluid and solid

    • Shuttle

      I am simulating a gap between rotor and stator. Oil is flowing in between, my domain is just the fluid, and the walls are having a constant temperature with thickness and shell conduction enabled. I don't understand the heat transfer from FLUENT. Is it then only unidirectional or bidirectional? I want both things to get influenced by changing temperature, oil and walls (based on their thermal conductivity). Should I always need solid domain? can fluent based on material and thickness simulate heat transfer two ways?

      Thank you for any suggestions!

      Heat will transfer hot to cold. If you've fixed the temperature of both sides of the fluid channel then the fluid temperature will adjust to suit the wall conditions. 

      What are you values are you setting, and what are you seeing? Posting images will help figure out what's going on.
