Numerical study of an evaporating meniscus on a moving heated surface
(American Society of Mechanical Engineers (ASME), 2004-07)The present study is performed to numerically analyze an evaporating meniscus on a moving heated surface. This phenomenon is similar to the one observed at the base of a vapor bubble during nucleate boiling. The complete ... -
Development of an experimental facility for investigating single-phase liquid flow in microchannels
(American Society of Mechanical Engineers (ASME), 2005-06)An experimental facility is developed to investigate singlephase liquid heat transfer and pressure drop in a variety of microchannel geometries. The facility is capable of accurately measuring the fluid temperatures, ... -
Characterization of the effect of surface roughness and texture on fluid flow - past, present, and future
(American Society of Mechanical Engineers (ASME), 2005-06)That surface roughness has an effect on fluid flow in networks has been understood for well over a century. The exact effect roughness has on fluid flow has not been completely understood, but a working estimate has ... -
High flux heat removal with microchannels - A roadmap of challenges and opportunities
(American Society of Mechanical Engineers (ASME), 2005-06)Heat fluxes in IC chips and other electronics equipment have reached the current limits of air cooling technology. Some of the applications require heat fluxes well beyond the limit of 100 W/cm2, requiring advanced ... -
Review of fabrication of nanochannels for single phase liquid flow
(American Society of Mechanical Engineers (ASME), 2005-06)The topic of single phase liquid flow in submicron or nanochannels is a nascent field. There have only been a couple papers that have dealt with this area directly. The most probable reason for this is that currently ... -
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 ... -
Single-phase liquid friction factors in microchannels
(American society of mechanical engineers (ASME), 2005-06)The validity of friction factor theory based upon conventional sized passages for microchannel flows is still an active area of research. Several researchers have reported significant deviation from predicted values, ... -
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 ... -
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 ... -
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 ... -
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 ... -

Multipass plate heat exchangers-effectiveness-NTU results and guidelines for selecting pass arrangements
(American Society of Mechanical Engineers (ASME), 1989-05)Plate heat exchangers are classified on the basis of number of passes on each side and the flow arrangement in each channel, taking into account the end plate effects. This results in four configurations each for the 1-1 ... -
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 ... -
