Thank you for the reply! It was along the lines I had expected. Is it Newton's law of cooling you refer to in the fluid/solid problem? I was considering a situation when the solid is not surrounded by a fluid domain big enough such that the heat transfer can be modeled by a boundary condition.
I have two different scenarios for heat transfer I need some help with understanding.
1.) Given two different materials in perfect contact with each other with no thermal resistance at the interface, what are the interface conditions at the interface? Considering two heat equations with...
