heat transfer via convection and conduction
heat transfer via convection and conduction
(OP)
Hi all,
I study Engineering and I have to simulate a heat Transfer for my Bachelor thesis. In my case the heat is transported via hot air over a rubber string and heats up the rubber surface through convection. In the next step the heat is transported through the rubber string via conduction.
My thought is, that I first calculate the part of heat flux of the given total heat flux in the canal, which heats the surface. In the next step I want to simulate the heat transfer through the material.
I only want to work with the user interface of abaqus, because unfortunately Iam not able to program.
First question: How can I separate the heat flux, which really hits the surface of the material, from the given heat flux in the heating canal? I know the flow Speed, the volume rate and the temp. of the hot air and the geometry of the rubber string.
Second question: How do I simulate the heat Transfer through the material? Which simulation typ is most accurate? surface film condition? concentrated film condition?
Third question: How do I create several time steps in Abaqus? When I simulate with surface film condition, the heat flux is only shown on the surface, but doesn't go through the material. In Addition I can only choose the BC and Loads in the Visualization. Any idea what went wrong?
I would be happy about any help!

That's conduction, and your subsequent comments suggest that you really don't understand any of the mechanisms at work.
