Conjugate heat transfer between coolant and two solids

Hello all


I am trying to simulate the conjugate heat transfer between a fluid in a pipe (acting as the coolant) and two solid bodies as illustrated in the attached figure,. The figure illustrates the resitances in the system:

1. Coolant (convective cooling)

2. Solid outer aluminium cape with a thickness of 7mm

3. Solid 0,5mm thick surface heat source with a fixed inlet temperature


The modeling is performed with the following settings:

- External

- Conjugate heat transfer in solids

- Timedependent

- Gravity


I am interested in estimating the outlet temperature of the (3.) solid and the cooling rate across the 180 [deg] circumference of the pipe.

Is a constant heat flux on the inlet of the solid a possibility or do one need to treat the (3.) solid as a "fluid" subdomain assigning a inlet flow with fixed temperature?
