I am doing a steady state thermal study on a simple Aluminum cylinder, enclosed from both sides. Inside the Al cylinder, there is an item (electronic component) in the center which is dissipating total heat of 50 Watt (see attached photo). The outside temperature on the cylinder is 40 degrees celsius.
For the analysis I am selecting the inner surfaces and applying a heat power of 50 Watt. Then I select the outside surface and apply a convection of 10 W/m2.K, with the ambient temperarture as 40 degrees. Is this the correct way to do the analysis? Thanks in advance.
