Abstract

An experimental investigation had been carried out in order to study the heat transfer performance of a vibrated two-phase closed thermosyphon tube. The working fluid used was R143a. The effects of heat flux (1276W/m2 ≤q≤ 6331 W/m2), filling percentage (30%≤V+≤5100%), the vibration dimensionless frequency (1.085≤ F ≤3.26), and the dimensionless amplitude (0.19 ≤ B ≤0.57) were studied. It was found that, the optimum filling percentage and the best dimensionless frequency values are 50% and 1.448, respectively. The Nusselt number had been correlated in a dimensionless form as a function of Kutateladze number, filling ratio, dimensionless frequency, dimensionless amplitude, and reduced pressure ratio.
