I was thinking about axisymmetry as well. The problem is that it will be in more complex system, where the cylinder will be fixed in some rectangular bodies and that's why I can't use that. That's a good idea, though! The heat transfer coefficient is easy to evaluate if you know the ambient...
It is FEA and it is a solid body. I don't expect an exact solution anyways. By performing a study on the 3D, I can see that by taking the bottom heat flux (x W/m2) and inputting as a volumetric heat flux (x W/m3) in the 2D doesn't give such a big discrepancy when evaluating the temperature...
Exactly. Well, it's not an easy task, but I'm sure that there are some artifices where the fluxes can be combined and use them in relation to the bottom heat flux, Cp and rho. Again, the problem is when dealing with the temperature difference because it's a dynamic one. I was thinking that...
Hey,
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...
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...
