Hi, I am a new Comsol modeler and I am trying to model a steel tanker filled with molten bitumen. The tanker is insulated and the bitumen is heated by two propane burners ( in form of U) located at the bottom. For the bitumen I have Non-isothermal Flow-Laminar , for the propane I guess Non-isothermal Flow (flow in a pipe) and also I have Heat transfer in solids for all solid structure and convection to the exterior.

I have tried many times to do my model and always I have some kind of message error.
Someone could give some directions to do this model. I am using Comsol 4.2a.

Thanks

Hi Misael,

Why are you explicitly modeling the propane? Why not just account for it as a distributed heat source. I suggest you start by going through one of the natural convection examples in the COMSOL Model Gallery such as this one: www.comsol.com/showroom/gallery/1448/.

I need to simulate the propane because my but is to analyze the different configuration of the heaters and their impact in the temperature profils,specifically , the risk of reaching ignition conditions.So there is one more problem , above the bitumen surface there is air (+bitumen gases) , and the temperature of the gaseus phase is critical to evaluate the risk of ignition.

I saw problems more complicated that this in Comsol , but...I cant do it !!
