The temperature of the heater is constant at 400K. The temperature at R1 is the same as the temperature of the heater, 400K. The fluid temperature is constant at 300K and this is the temperature of the surrounding sheath at R2. Given the symmetry of the system, it will enough for the analysis to define a subdomain in 2D as shown below. Solution using Comsol Graphical User Interface. 1. To start Comsol, click the icon COMSOL Multiphysics 3.2 2. In the Model Navigator window we must choose the type of coordinate system that we want to use to solve our problem. As mentioned above, our problem is pretty symmetric and therefore a 2D system (which is the default value) will be enough.
3. Next, we need to provide information about the application modes (or PDE’s) that must be taken into consideration in order to solve our problem. In accordance with the statement, the problem can be solved considering only conductive heat transfer. Hence, we must select this application mode and to do so, we must double-click the option COMSOL multiphysics. 4. Next, we double click on the option Heat Transfer. 5. Next, select the option Conduction by doing one click on the symbol “+” to the left. In doing so two new options will show up. We must pick one of them depending on the type of regime we will use to solve our problem. For our case we select Steady-state analysis doing one click on this option.
