RIT Undergraduate Symposium 2008
(Rochester Institute of Technology, 2008-08)
The Undergraduate Research Symposium was founded to honor student achievement in scientific research and to further RIT's goal of combining traditional laboratory work and classroom instruction with experiential learning. ...
Numerical study of the effect of inlet constriction on bubble growth during flow boiling in microchannels
(American society of mechanical engineers (ASME), 2005-06)
Flow boiling through microchannels is characterized by
nucleation of vapor bubbles on the channel walls and their
rapid growth as they fill the entire channel cross-section. In
parallel microchannels connected through ...
Numerical simulation of flow through microchannels in bipolar plate
(American society of mechanical engineers (ASME), 2005-06)
In this paper, the flow through a serpentine microchannel
with obstructions on wall is studied. Various obstruction geometries
ranging from rectangular to triangular are considered. For
each geometry pressure drop across ...
Experimental evaluation of pressure drop elements and fabricated nucleation sites for stabilizing flow boiling in minichannels and microchannels
(American society of mechanical engineers (ASME), 2005-06)
The flow boiling process suffers from severe instabilities
induced due to nucleation of vapor bubbles in a minichannel or
a microchannel in a superheated liquid environment. In an
effort to improve the flow boiling ...
Single-phase liquid heat transfer in microchannels
(American society of mechanical engineers (ASME), 2005-06)
The development of advanced microchannel heat
exchangers and microfluidic devices is dependent upon the
understanding of the fundamental heat transfer processes that
occur in these systems. Several researchers have ...
Effects of repeating microstructures on pressure drop in rectangular minichannels
(American Society of Mechanical Engineers (ASME), 2005-06)
A literature review in laminar incompressible flow in
microchannels has shown both early and late transitions from
laminar to turbulent flow as well as no deviation from the
conventional flow transition of Re=2300. In ...
Effect of entrance condition on frictional losses and transition to turbulence in minichannel flows
(American Society of Mechanical Engineers (ASME), 2004-06)
In studying the fluid flow and heat transfer in
microchannels and minichannels, various claims have been
made regarding transition at Reynolds numbers significantly
below 2300. As a first step in identifying the reasons ...
Optimization of microchannel geometry for direct chip cooling using single phase heat transfer
(American Society of Mechanical Engineers (ASME), 2004-06)
Direct cooling of an electronic chip of 25mm x 25mm
in size is analyzed as a function of channel geometry for
single-phase flow of water through small hydraulic
diameters. Fully developed laminar flow is considered ...
Effect of gravitational orientation on flow boiling of water in 1054 x 197 micron parallel minichannels
(American Society of Mechanical Engineers (ASME), 2004-06)
Microchannels and minichannels are being considered for high heat flux applications under microgravity environment in space missions. Due to the small hydraulic diameter, the effect of gravitational forces on flow boiling ...
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 ...
