Hello everyone. I`m trying to develop a particular heat exchanger. It`s a cylindrical vessel with an inner spiral wich delivers the heat. The domain has cylindrical shape and the spiral is at the center of the domain. I`m just starting to deal with this software and, after a couple of tries, none of the results (Temperature gradients) seems to behave like it should, I mean natural convection. What should i do?

Thanks.

hello i would like to send me about steps of natural convection modeling with fv method thank you
