COUPLED SIMULATION OF MULTIPHASE FLOW AND HEAT TRANSFER IN A JACKETED VESSEL

This paper presents a coupled method to simulate flow and heat transfer in jacketed vessels, in which the complicated interactions between the vessel and the jacket are taken into account. The coupled simulation of a jacketed vessel of 2.00 m in diameter is carried out to investigate the heat transfer process. The results show that thermal boundary conditions of the fluids are nonuniform. When compared with simulation using uniform boundary conditions, significant differences are observed in the distribution of heat flux and heat transfer coefficient. The comparison results indicate that the thermal boundary condition has a significant influence on heat transfer in jacketed vessels.
