HEAT TRANSFERT ANALYSIS OF MIXED CONVECTION IN A HEATED CAVITY
摘要
In this paper, we present an experimental investigation of turbulent combined free and forced convection heat transfers in an isothermal cubical cacity opened on one face. Correlations between Nusselt number (Nu), Reynolds number (Re) and Grashof number (Gr) are determined in the range 5.5 103 < Re < 4.5 104 < 2, these correlations can be expressed as Nu = NUn(1+c(Re/Gr½)d), where Nun corresponds to pure natural convection and Ñ and d are functions of angles α and φ.
