Tridimensional study of the natural convection and the entropy generation in a solar collector equipped with partitions.

Étude tridimensionnelle de la convection naturelle et de la génération d'entropie dans un capteur solaire équipé de partitions.

Author(s) : YEJJER O., KOLSI L., NACEUR BORJINI M., et al.

Summary

This work presents a tridimensional numerical study of the natural convection and the entropy generation in an inclined solar collector equipped with five equidistant partitions. A parametric study is made for various partitions lengths and Rayleigh numbers while Prandtl number was fixed at Pr=0.71 and the inclination angle is 45°. Results are reported in terms of iso-surfaces of temperature, isotherms, particles trajectories, vector velocity projection, average Nusselt number along the absorber plate and entropies generation contours.
