| Heat transfer characteristics of a vertical flat thermosyphon (VFT) W. Srimuang/S. Rittidech/B. Bubphachot
The Journal of Mechanical Science and Technology, vol. 23, no. 9, pp.2548-2554, 2009
Abstract : This paper presents an experimental investigation on the heat transfer characteristics of a vertical flat thermosyphon
(VFT). Several tests were performed to assess the effects of filling ratios, hydraulic radius, working fluid, and aspect
ratio (Le/4HR) at a vertical orientation on the heat transfer characteristics of the VFT. It was found that the filling ratios
and hydraulic radius affect heat flux; while the aspect ratios of VFT increased, the heat flux decreased. In addition, the
working fluid changed from water and ethanol to R123 as the heat flux increases.
