Modeling Heat Generation in 2D
Modeling Heat Generation in 2D
(OP)
Hey All,
If I want to model a cylinder that has a heat source (a heater) at the bottom. I want to model it using the heat equation in 2D (in the radial direction), how can I account for the bottom heater? I need to find a relation between the bottom heat flux and the volume heat source. I appreciate any help!

RE: Modeling Heat Generation in 2D
What do you mean by "account for?"
What "volume heat source?" Is there another heater besides the "bottom heater?"
Is this for school? Student posting is not allowed.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

RE: Modeling Heat Generation in 2D
Thanks for the answer! It is a 2D problem because I want to analyze the radial direction. If we look at a 3D scenario, the bottom heater (which is the only heater of the system) gives a heat flux at the bottom and some of energy is conducted and stored in the volume, while the rest is dissipated by convection through the surfaces. Now, looking at a 2D geometry in the radial direction, I want to account for the heat flux that enters the system at the bottom and use it for the analysis. Basically, I need a relation between the heat flux at the bottom, the heat storage and the heat flux that is leaving the radial direction. I have the option to include the heat flux as a volumetric heat source. That is, the heat flux (W/m2) at the bottom should be expressed as a volumetric heat source (W/m3) by using some artifices that I'm not sure yet how to express. The problem is also time dependent and that gives more headache.
P.S. t is not for school. I don't think this is a class problem :)
