Paper Title :
Effect on Surface Vibration on Flow Boiling Heat Transfer of R-600a in a Vertical/Parallel Circular Tube with Metallic Porous Inserts

Article Citation :Mao-Yu Wen ,Ching-Yen Ho , (2019 ) " Effect on Surface Vibration on Flow Boiling Heat Transfer of R-600a in a Vertical/Parallel Circular Tube with Metallic Porous Inserts " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 41-46, Volume-7,Issue-8

Abstract : This study carried out an experiment to investigate the characteristics of sub-cooled flow boiling heat transfer of a hydrocarbon refrigerant R600a (isobutane) flowing in a vertical circular pipe within dispersed-copper porous inserts under surface vibration. The experiment was performed at a saturation temperature of 10°C. Vapor qualities were from 0.076 to 0.89, and there was a mass flux of 105 – 1085 kg/m2s and a heat flux of 12-65 kW/m2 . The effects of surface vibration and the geometries of the inserts (the mean pore diameters, porosity and permeability) on the heat transfer of R-600a were presented. In addition, comparisons were made with a horizontal pipe having the same geometry and experimental conditions Keywords - R600a,Vertical/ Parallel Flow Boiling, Heat Transfer, Surface Vibration, Dispersed-Copper Porous Inserts Sixth Term
