Abstract Conjugate conduction and convection heat transfer problems are often solved numerically in a unitary computational domain containing both the solid and fluid regions. When SIMPLE-like algorithms are employed in the computation, one has to pay close attention to the peculiarity of the energy equation or to the problem how to ensure the continuity of heat flux at the fluid–solid interface. For this reason, two approaches, i.e., the ‘pseudo-density’ method and the ‘pseudo-solid-specific-heat’ method, are suggested, respectively, for the solution of the energy equation, and typical computed results are presented.
