CONVECTION AND HEAT TRANSFER AROUND A CYLINDER ON THE SECOND ROW OF A BANK IN AN AIR STREAM CHARGED WITH SPRAYED WATER.

ETUDE DES STRUCTURES CONVECTIVES ET DU TRANSFERT THERMIQUE AUTOUR D'UN CYLINDRE EN DEUXIEME NAPPE DANS UNE CONFIGURATION EN QUINCONCE, EN ECOULEMENT D'AIR CHARGE DE GOUTTELETTES D'EAU.

Summary

THE AUTHORS DESCRIBE AN EXPERIMENTAL STUDY OF THE INFLUENCE OF LONGITUDINAL AND TRANSVERSAL PITCH ON THE CONVECTIVE TRANSFER AROUND A CYLINDER ON THE SECOND ROW OF A THREE CYLINDER STAGGERED BANK, OPERATING IN AN AIR STREAM CHARGED WITH SPRAYED WATER AT MODERATE REYNOLDS NUMBER. THE ANALYSIS SHOWS THE EFFECTS OF GEOMETRICAL PARAMETERS ON VARIOUSCHARACTERISTIC ZONES OF THE FLOW: LAMINAR BOUNDARY LAYER, SEPARATION AND VORTICES. THE MODIFICATIONS OF LOCAL NUSSELT NUMBER EVOLUTION COMPARED WITH THE SINGLE CYLINDER ARE EXPLAINED. FOR THE DISPOSITION WHICH GIVES THE HIGHEST HEAT TRANSFER, A CORRELATION OF LOCAL NUSSELT NUMBER IS PROPOSED.
