Resumo: This paper aims to renew interest on mixed thermal convection research and to emphasize three issues that arise from the present analysis: 1) a clear definition of the reference temperature in the Boussinesq approximation; 2) a practical delimitation of the three convective modes, which are the forced convection (FC), mixed convection (MC) and natural (or free) convection (NC); 3) and, finally, a uniform description of the set FC/MC/NC in the similarity framework. The planar case, for which analytical solutions are available, allows a detailed illustration of the answers here advanced to the above issues.
