Two-phase flow oscillations in microchannel convective boiling

2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS), 2007
A thermal microsystem with integrated heaters, pressure and temperature microsensors, has been fabricated to study local temperature and pressure fluctuations occurring in forced convective boiling in microchannels. The observed two-phase flows can be classified into two patterns: oscillating liquid/vapour interface and liquid burst flow; both leading ...

A Stabilized Boiling/Evaporation Two-Phase Flow in Microchannels

ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 2, 2009
The high degree of instability in boiling two-phase flow in parallel microchannels is a widely recognized phenomenon. However, if the maldistribution of flow is eliminated and the generated vapor is discharged smoothly through the careful design of the inlet and outlet plenums, in addition, by using part of each channel as a virtual throttle to depress

Two-Phase Flow Boiling in a Microchannel Heat Sink

Micro-Electro-Mechanical Systems (MEMS), 2001
Abstract A micro heat sink comprising 10 microchannels integrated with a local heater and a temperature microsensor array has been fabricated on a silicon wafer using standard micromachining techniques. A glass wafer was anodically bonded to the silicon wafer in order to cap the trapezoidal microchannels, about 14μm in depth and 120μm in

Characteristics of Two-Phase Flow Boiling in Microgap Channel

2013
The current chapter presents the heat transfer and pressure data of three different dimension microgap heat sinks collected during the experimental program. Experimental results are discussed to characterize the two phase flow boiling heat transfer and pressure drop behaviors in microgap channel.

Prediction of a subcooled boiling flow with advanced two-phase flow models

Nuclear Engineering and Design, 2012
a b s t r a c t Prediction of bubble size which governs interfacial transfer terms between the two phases is of impor- tance for an accurate prediction of the subcooled boiling flow. In the present work, a mechanistic bubbles size model, Swas examined to enhance the prediction capability of subcooled boiling flows for the CFD (computational fluid ...

Stability of the Boiling Two-Phase Flow of a Magnetic Fluid

Journal of Applied Mechanics, 2007
Elucidation of magnetic stabilization of boiling two-phase flow by utilizing the magnetization of the fluid is proposed herein. The effect of magnetic field on the stability of the boiling two-phase pipe flow of the magnetic fluid under a nonuniform magnetic field is investigated both theoretically and experimentally.

The Boiling Crisis Phenomenon in Two-phase Flow

1987
An analytic model of the flow boiling crisis in annular flow (at high vapour quality) and own experimental results of Freon 21 are presented in the paper. The model is based on the analysis of the film drying process on the channel wall, thus expressing the mass balance of both the film and the core by means of differential equations.
