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 ...
Effect of channel roughness on heat transfer and fluid flow characteristics at low Reynolds numbers in small diameter tubes
(American Society of Mechanical Engineers (ASME), 2001-06)
The effect of roughness on pressure drop and heat transfer
in circular tubes has been extensively studied in literature.
The pioneering work of Nikuradse (1933) established the sand
grain roughness as a major parameter ...
High-Speed photographic observation of flow boiling of water in parallel mini-channels
(American Society of Mechanical Engineers (ASME), 2001-06)
The use of smaller passage dimensions is becoming more
prevalent in flow boiling applications. Passages with hydraulic
diameters on the order of 1mm provide higher heat transfer
coefficients resulting in more compact ...

Critical heat flux in subcooled flow boiling - An Assessment of current understanding and future directions for research
(Begell House Inc., 2001)
Critical Heat Flux, or CHF, is an important condition that
defines the upper limit of safe operation of heat transfer equipment
employing boiling heat transfer in heat flux controlled systems. Although
significant ...
