TL;DR: In this paper, a flat plate EHD heat pipe was investigated in order to investigate the maximum heat transport capahility and dry out conditions and the result indicates that relatively stable and high performance devices are possible.
Abstract: An experiment of flat plate EHD heat pipe was performed in order to investigate the maximum heat transport capahility and dry out conditions. The result indicates that relatively stable and high performance devices are possible. The EHD tent flow structures at evaporator and condenser sections were observed in order to investigate the effect of a variation of flow structures by heat transport and applied voltage on the dry out heat flux at an evaporator. The dry out of liquid flow at the evaporator caused by a variation of crosssectional area of EHD flow structure exerts a considerable effect to heat pipe performance.

TL;DR: The use of two-phase closed thermosyphons (TPCTs) is increasing for many heat transfer applications as mentioned in this paper, and the most recent published experimental and theoretical studies on the TPCTs are reviewed.
Abstract: The use of the two-phase closed thermosyphons (TPCTs) is increasing for many heat transfer applications. This paper reviews the most recent published experimental and theoretical studies on the TPCT. After a description of the TPCT operating principle and the performance characteristics, the heat transfer analysis in condenser and evaporator sections that depends on the complex two-phase process are described. The influence of the affecting parameters on the performance of TPCTs such as the geometry (diameter, shape and length), the inclination angle, the filling ratio (FR), the working fluid, the operating temperature and pressure analyzed by various researchers is discussed. The various operating limits occurring in a thermosyphon includes viscous, sonic, dryout, boiling and flooding are also analyzed. Considering the application of TPCTs, the paper presents a review of experimental tests and applications. This paper can be used as the starting point for the researcher interested in the TPCTs and their renewable energy applications.
