    Conjugate heat transfer between coolant and two solids

    Admir Jonuz

      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?
