Effect of entrance condition on frictional losses and transition to turbulence
(American Society of Mechanical Engineers (ASME), 2002-11)
In studying the fluid flow and heat transfer in
microchannels, various claims have been made regarding
transition at Reynolds numbers significantly below 2300. As a
first step in identifying the reasons for such early ...
Fundamental issues related to flow boiling in minichannels and microchannels
(Elsevier, 2002-09)
Flow boiling in small hydraulic diameter channels is becoming increasingly important in many diverse
applications. The previous studies addressing the effects of the channel size on the flow patterns, and heat transfer ...
Effects of Weber number and surface temperature on the boiling and spreading characteristics of impinging water droplets
(American Society of Mechanical Engineers (ASME), 2002-06)
In the present work, the effects of Weber number and
surface temperature upon the droplet impingement behavior and
boiling characteristics have been experimentally studied. High
speed photography (up to 8000 frames per ...
Transient thermal analysis of a microprocessor using a heat spreader with variable thermal storage characteristics
(American Society of Mechanical Engineers (ASME), 2002-04)
The thermal performance of a heat spreader with Phase
Change Material (PCM) is investigated experimentally under
transient conditions. The transient thermal load generated by a
microprocessor is obtained by running a ...
Contact angles and interface behavior during rapid evaporation of liquid on a heated surface
(Elsveier, 2002-02-16)
Photographic observations of the boiling phenomena have played an important role in gaining insight into the
boiling mechanism. This paper presents a brief historical review of the available literature on the photographic ...

Two-phase flow patterns, pressure drop and heat transfer during boiling in minichannel and microchannel flow passages of compact evaporators
(Taylor & Francis, 2001-12)
The small hydraulic diameters employed during flow boiling in
compact evaporator passages are becoming more important as they
are employed in diverse applications including electronics cooling
and fuel cell evaporators. ...
A Theoretical model to predict pool boiling CHF incorporating effects of contact angle and orientation
(American Society of Mechanical Engineers, 2001-12)
A theoretical model is developed to describe the hydrodynamic behavior of the vapor liquid
interface of a bubble at the heater surface leading to the initiation of critical heat
flux (CHF) condition. The momentum flux ...
A Photographic insight into the motion of liquid-vapor interface during rapid evaporation of a liquid droplet on a heated surface
(American Society of Mechanical Engineers (ASME), 2001-11)
Photographic observations of the boiling phenomena have
played an important role in gaining insight into the boiling
mechanism. This paper presents a brief historical review of the
available literature on the photographic ...
Molecular dynamics simulation and measurement of contact angle of water droplet on a platinum surface
(American Society of Mechanical Engineers (ASME), 2001-11)
A water liquid droplet in contact with a platinum surface
was simulated by the molecular dynamics method. Water
molecules were modeled by SPC/E and one layer of harmonic
molecules represented the platinum surface with ...
