Title

NUMERICAL MODELING OF HEAT TRANSFER AND PRESSURE DROP IN A MODIFIED SOLAR HEATER USING COMPUTATIONAL FLUID DYNAMICS

Pages

  33-44

Abstract

 In this paper, a numerical modeling of heat transfer and turbulent flow in a SOLAR HEATER with Delta-Winglet VORTEX GENERATORs is presented. Calculations by the finite volume are conducted using the SIMPLE algorithm.Air turbulent flow with various mass flow rates under the Reynolds number of 5000-22000 was investigated. The CFD predictions were compared with the experimental data and good agreement was observed. The results showed that NUSSELT NUMBER and FRICTION FACTOR in a system fitted with combined rib and delta-winglet VORTEX GENERATORs are higher than those of traditional ribbed systems. In addition, a system fitted with combined ribbed top and bottom walls and VORTEX GENERATORs through the inlet was proposed, and increase in NUSSELT NUMBER was shown in comparison with previous systems.
