The geyser effect in a two-phase thermosyphon

International Journal of Heat and Mass Transfer, 1983
Abstract An interesting phenomenon, which was observed during experimental research work carried out on a two-phase thermosyphon with water as the working fluid, is described. The phenomenon is a pulsed boiling at low pressure and was called the “Geyser Effect”.

The Evaporative, Tubular Thermosyphon

1992
Abstract Above the critical pressure, the tubular thermosyphon behaves as a singlephase system. The same is often true below the critical pressure provided that the fluid specific volume is very much different from the critical value. As Fig.

Thermosyphon Heat Exchangers

2020
One of the most common use of a thermosyphon assisted equipment in industry is in heat exchangers. In this chapter, the methodology to be used for the design of thermosyphon heat exchangers is presented, including the specification of the thermosyphons (geometry, materials, etc) and the arrangement of the thermosyphon tubes.

The Rotating, Tubular Thermosyphon

1992
Abstract At first glance, it may seem that the replacement of gravitational acceleration by centrifugal acceleration is a minor change, and indeed it is often assumed that heat and mass transfer relations in a rotating field may be obtained from those in a uniform gravitational field by this simple substitution.

Entry effects in the open thermosyphon

Journal of Fluid Mechanics, 1964
In this paper flow-visualization techniques are used to study the flow instability which occurs at the orifice in the free convection open thermosyphon. The influence of the shape of the orifice on the measured heat transfer of the system is also studied under both laminar and turbulent conditions.

Advances in Thermosyphon Technology

1973
Publisher Summary Thermosyphon applied in formal studies are the systems that have the intrinsic function of removing heat from a prescribed source and transporting heat and mass over a specific path, and rejecting the heat and or mass to a prescribed sink— that is, the path of the circulating flow that transports the thermal energy is or can be ...

The Simple, Tubular Thermosyphon

1992
Abstract Newton’s law of cooling, in which the rate of cooling of a body is taken to be proportional to its temperature measured relative to that of the environment, is the first quantitative statement ever made about natural convection. Implicit within this law is the requirement that the heat transfer coefficient at the body surface

Natural convection in the cranked thermosyphon

International Journal of Heat and Mass Transfer, 1993
Abstract The paper presents the results of an experimental investigation of the heat transfer characteristics of the cranked, tubular thermosyphon under single phase conditions. Using water in a small scale rig, data have been obtained for 10 5.9 Ra 7.5 , and have been plotted in the usual form of Nu vs Ra .

Thermosyphon circulation in solar collectors

Solar Energy, 1980
Abstract Theoretical predictions of flow rate in thermosyphon solar collectors are compared with experimental measurements obtained using a laser doppler anemometer. Modifications to the usual method of analysis are proposed to improve the accuracy of the predictions, and the results are compared with flow rate predictions and measurements in other ...

Thermosyphon system potential

Domestic hot water (DHW) is already the single largest slice of household energy—about one quarter of all residential demand—and is poised to rise further. Demographers project global population to swell past ten billion by mid-century, while rapid urbanisation and higher living standards are equipping millions of new apartments with showers, washing ...
