Hello,
I am currently working on the design of a thermal energy storage, and I would like to study convection and conduction in a closed-circuit flow, using an interior fan, but my model does not converge.
The model is described in the picture or in the Comsol file attached.
A double pipe in placed inside a tank. In the inner diameter of the pipe flows hot air with known parameters. In the outer diamater flows water, which enter at the bottom of the tank and exit at the top.
Am I using the interior fan node the wrong way? Do I necessarily need to put an inflow and an outflow node in the water tank part (because I feel like the software doesn't like that the tank where is applied 'turbulent flow' is nearly motionless) ?
Thank you in advance !
