This study analyzes the effect of heat generation and internal wall thickness on the convective heat transfer characteristics of laminar flow with multi-flow in a circular, annular tube maintained under uniform wall temperature. Fluid in each flow section is assumed to have different but arbitrary uniform heat generation densities. The temperature fields in the inner and outer passages are obtained analytically from the energy equation by employing the successive approximation method. Based on these temperature fields, the expressions of Nusselt number on the outer surface and on the internal dividing surface corresponding to different heat generation combinations, are derived. The curves, representing the outer and inner Nusselt numbers, including the effect of internal wall thickness and heat generation considering the Molten Salt Breeder Reactor (MSBR) operation, are plotted against the dimensionless radius of the separation surface.
