Evaluation of single phase flow in microchannels for high flux chip cooling - Thermohydraulic performance enhancement and fabrication technology
(American Society of Mechanical Engineers (ASME), 2004-06)
The increased circuit density on today’s computer chips
is reaching the heat dissipation limits for air-cooled
technology. Direct liquid cooling of chips is being
considered as a viable alternative. This paper reviews ...
Experimental study of heat transfer, pressure drop, and dryout for flow boiling of water in an oil heated minichannel
(American Society of Mechanical Engineers (ASME), 2004-06)
Heat transfer and pressure drop, are experimentally
recorded for flow boiling water in a single 706 mm circular
copper channel 158.75 mm long. Heat is supplied by heat
transfer oil at specified temperatures to a helical ...
Heat transfer mechanisms during flow boiling in microchannels
(American Society of Mechanical Engineers, 2004-02)
The forces due to surface tension and momentum change during evaporation, in conjunction
with the forces due to viscous shear and inertia, govern the two-phase flow patterns
and the heat transfer characteristics during ...

Single-phase heat transfer enhancement techniques in microchannel and minichannel flows
(American Society of Mechanical Engineers (ASME), 2004)
The single-phase heat transfer enhancement techniques
are well established for conventional channels and compact
heat exchangers. The major techniques include flow
transition, breakup of boundary layer, entrance ...
An Extension of the flow boiling correlation to transition, laminar and deep laminar flows in minichannels and microchannels
(Taylor & Francis, 2004)
Flow boiling in mini- and microchannels offer very high heat transfer capabilities and find
applications in many emerging technologies, such as electronics cooling and fuel cells. The low flow
rate employed in such ...
High speed photographic observation of flow patterns during flow boiling in single rectangular minichannel
(American Society of Mechanical Engineers (ASME), 2003-07)
The present study extends the range of flow patterns
observed during boiling of water in a single minichannel of
height 197 mm and width 1054 mm. The calculated hydraulic
diameter of the channel is 333 mm. High-speed ...
Heat transfer from a moving and evaporating meniscus on a heated surface
(American Society of Mechanical Engineers (ASME), 2003-07)
A stable meniscus is formed between a needle dispensing water over a heated circular face of a rotating copper block. The needle is offset from the axis of rotation and thus forms a moving meniscus. The water flow rate, ...
Heat transfer mechanisms during flow boiling in microchannels
(American Society of Mechanical Engineers (ASME), 2003-04)
The forces due to surface tension, inertia, and momentum change during evaporation in microchannel govern the two-phase flow patterns and the heat transfer characteristics during flow boiling. These forces are analyzed in ...
Critical heat flux in microchannels: Experimental issues and guidelines for measurement
(American Society of Mechanical Engineers (ASME), 2003-04)
Critical heat flux limit is an important consideration in the design of any flow boiling unit. Before the use of microchannels under flow boiling conditions becomes widely accepted in critical applications, such as electronics ...
