Abstract

•Dissipated convective heat strongly depends on convection coefficient. Two correlations were developed for so and validated.•A clear error in air temperature distribution along the heat sink was seen if coefficient were not properly selected.•The error decreases when thermal-entry length effect is considered, as for thermal flow through short conduits as Pr <1.
