The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both the fluid and the solid generating power. A suitable validation framework has been set up on the basis of an ad hoc analytic solution for both velocity and temperature fields inside the fluid and the solid regions.
