Nowadays thermal analyses for building applications are mostly carried out by the help of thermal and fluid analysis software instead of experiments because of saving time and cost. The analysis software solves the cases based on both analytical equations for such as conductive and radiative heat transfer and empirical equations and models for convective heat transfer. The key point of the numerical analysis is assigning an appropriate empirical correlation or initial parameter that suits the case as close as possible. Several studies in the literature have argued that a case affected by both buoyant and mechanical forces is defined as “mixed flow” and it should not be solved by natural or forced convection correlations. Therefore, these cases need their own correlations called as mixed convection correlations (or blended correlations in some literature). In this study, mixed convection correlations are briefly scrutinized. In addition, some of the widely accepted empirically validated correlations for mixed convection heat transfer coefficient were tabulated and reviewed.
