The evaporating water droplets on a horizontal heated substrate were experimentally studied. The constantan foil 25 μm thick with a size of 42× 35 mm 2 was used as a substrate …
Evaporating water drops on a horizontal heated substrate were investigated experimentally. The heater was made of a constantan foil with the thickness of 25 μm and size of 42× 35 …

A wickless heat pipe was operated on the International Space Station to provide a better understanding of how the microgravity environment might alter the physical and interfacial …
The Constrained Vapor Bubble (CVB) experiment concerns a transparent, simple,“wickless” heat pipe operated in the microgravity environment of the International Space Station (ISS) …

Previous studies on wickless heat pipes showed that a temperature induced “Marangoni flow” prevents liquid from recirculating to the heater end, and therefore reduces the …
The effect of cooling temperature on heat pipe performance has generally received little consideration. In this paper, we studied the performance of a Constrained Vapor Bubble …
Bubble nucleation was investigated in a 20-mm-long, wickless heat pipe on the International Space Station. Over 20 h of running experiments using pentane as the working fluid, more …
