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.
