摘要

This paper presents a numerical analysis of the interaction of natural convection dominated melting inside a rectangular enclosure coupled with forced convection heat transfer in a transport fluid via a finite conductance heat exchanging surface. Experiments were carried out for Rayleigh numbers, Ra, between 2×08× l08 and 4× 60 × l09, modified Reynolds numbers, Re between 4.23 and 423.0, wall-PCM thermal diffusivity ratios, α , between 5.0 and 10.0 and dimensionless wall thickness, w, between 0.005 and 0.05. Results show that heat transfer from the HTF to the PCM and, consequently, the melting process are strongly dependent on the possible complex combinations of the HTF dynamic and thermal conditions and of the properties of the heat exchanging surface.
