Study on Heat Pipe : 2nd Report, Heat Transfer Mechanizm in the Evaporator Zone of Heat Pipe
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1979 The primary object of this study is to gain a better understanding of the heat transfer mechanism in the evaporator of a heat pipe. To evaluate the effects of working pressure, working fluid, pipe inclination and noncondensable gas on the heat transfer mechanism, sintered powders were used as the wick, and pure water and R113 as the working fluid ...

Evaporative Heat and Mass Transfer from the Free Surface of a Liquid Wicked into a Bed of Spheres
, 2011 Evaporation of ethanol from square packed arrays of 3.95 mm diameter copper spheres in a transparent, enclosed chamber is investigated. The enclosure ensures that relatively saturated vapor conditions exist near the free surface. The desired heat flux is

Physics Procedia, 2015 AbstractThis paper reports on the development and the thermal tests of three superfluid helium heat pipes. Two of them are designed to provide a large transport capacity (4 mW at 1.7K). They feature a copper braid located inside a 6mm outer diameter stainless tube fitted with copper ends for mechanical anchoring. The other heat pipe has no copper braid

A study on self-rewetting fluids for heat transfer in microgravity
, 2009 In a number of water alcohols solutions the surface tension is an increasing function of temperature. Such mixtures are generally referred as self-rewetting fluids because convection driven by a reverse Marangoni effect is direct from cold to hot region ...
