WebThe boundary thermal condition of the structure is generally divided into four categories, [0-9] depending on the different conditions of the environment surrounding the structure and heat exchanging with the surrounding medium: 1. It is known that the temperature on the boundary ( l1) of the structure is a function of time ( t ), e.g., (5.8) 2. WebCalculate the wall heat-flux.

If you are modeling the fluid side only, you do not need to do anything to have an adiabatic condition. If you are modeling the wall, the heat transfer coefficient will be computed and not an input at the interface of the fluid/solid. 2. The thermal conductivity can be inputted without using a UDF in a number of ways.
