Presents basic and advanced techniques in the analytical and numerical modeling of
various heat pipe systems under a variety of operating conditions and limitations. It
describes the variety of complex and coupled processes of heat and mass transfer in heat  …

Abstract A one-dimensional, steady state analysis of the heat and mass transfer in porous
media saturated with the liquid and vapor phases of a single component fluid was
conducted. The effects of capillarity, gravity forces, and phase change were included …

A new, well‐defined metal vapor device called the heat‐pipe oven has been developed on
the basis of the heat pipe, a heat conductive element designed by Grover and his co‐
workers in Los Alamos. It continuously generates homogeneous vapors of well‐defined …

Abstract Nanofluid is employed as working medium for conventional circular heat pipe. The
nanofluid used in the present study is an aqueous solution of various-sized gold
nanoparticles. The thermal resistance of heat pipe with nanofluid or with DI water was …

Abstract A model for the radial heat transfer of a grooved heat pipe evaporator is presented.
It combines the solution of a two-dimensional heat conduction problem with the calculation
of the shape of the liquid-vapour interface and its temperature, taking into account the …

Abstract Nano-fluid is employed as the working medium for a conventional 211 μm wide×
217 μm deep grooved circular heat pipe. The nano-fluid used in this study is an aqueous
solution of 35 nm diameter silver nano-particles. The experiment was performed to measure …

By combining nanofluids with thermally excited oscillating motion in an oscillating heat pipe
(OHP), we developed an ultrahigh-performance cooling device, called the nanofluid
oscillating heat pipe. Experimental results show that when the OHP is charged with …

Abstract Flow visualization was conducted for the closed-loop pulsating heat pipe (PHP)
using a charge coupled device (CCD). It was observed that during the start-up period, the
working fluid oscillates with large amplitude, however, at steady operating state, the working …

A structure of a loop-type heat pipe is disclosed in which a heat carrying fluid, preferably a bi-
phase non-condensative fluid, circulates in a loop form in itself under its own vapor pressure
at a high speed within an elongate pipe so as to repeat vaporization and condensation, thus …
