The heated fin consists of an inverted "T" shape placed in a closed box. The only boundary specifications required for this analysis are wall thermal conditions. A fixed temperature of 343 K needs to be applied to the base of the solid fin to provide the heat source. The vertical sides of the fluid-containing box need to be set to a fixed temperature of 293 K. All other wall boundary conditions will be considered to be adiabatic, which is the default condition. A contact-type conducting boundary will also be used at the solid-fluid interface.
We will start with the wall boundary definitions for the fluid region.
The temperature value for this boundary can now be set.
The conditions for the Horizontal-Walls boundary (upper and lower walls of the fluid region) will be left at the default adiabatic setting.
We can now set the solid wall boundary conditions and values in a similar way to the fluid ones.
The temperature value for this boundary can now be set.
