Visualization of Flow Pattern in Thermosyphon by ECT

AIP Conference Proceedings, 2007
An investigation on the visualization of the flow of the liquid in a two‐phase closed thermosyphon (TPCT) is carried out. Electrical capacitance tomography (ECT) with optimal step lengths for iterative image reconstruction algorithm is applied in the study. Measurements are made under a range of heating rates of the TPCT.

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 Tubular Thermosyphon

1992
Abstract The tubular thermosyphon is a very simple idea for transferring heat. Fluid inside a tube is circulated by buoyancy forces and thus carries thermal energy from the hot end to the cold end with great efficiency. The device has many uses: freezing ground, cooling equipment and machinery, waste heat recovery, and energy ...

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.

NATURAL CONVECTION IN C-SHAPED THERMOSYPHON

Numerical Heat Transfer, Part A: Applications, 1997
The present work is concerned with the numerical analysis of natural convection from a C-shaped thermosyphon. The system can be considered as a model for a Trombe wall in passive solar collectors as well as electronic cooling arrangements and it has geophysical applications. The effect of Rayleigh number (1 {times} 10{sup 3} to 1 {times} 10{sup 7}) and

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 Boiling in Vertical Channels

Journal of Heat Transfer, 1985
The high heat flux capability and modest temperature differences associated with boiling heat transfer make immersion cooling one of the primary candidates for VHSIC and VLSI microelectronic component thermal control. While the literature contains many references to pool boiling heat transfer from single integrated circuit packages or transistor cans ...

Observations on an Evaporative, Elbow Thermosyphon

Journal of Heat Transfer, 1993
The performance of the evaporative elbow system was found to be superior to that of the nonevaporative system, but comparable to the performance of the linear system. The parametric role of the evaporator wall temperature, the condenser wall temperature, and the vapor saturation temperature was demonstrated, each revealing a similar monotonic effect ...

Condensation in a gas-loaded thermosyphon

International Journal of Heat and Mass Transfer, 1995
Abstract An experimental and modelling study is reported of condensation in a cylindrical, two-phase reflux thermosyphon containing non-condensable gas. The diffusion equations in the interface region are solved numerically. The spatial distribution of condensing heat flux is determined from accurate measurements of the thickness of the condensed ...

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.
