Two-phase flow patterns in two horizontal microchannels with uniform reentrant cavities in sidewall were experimentally studied, using deionized water and air as working fluids. The hydraulic diameter of microchannels in the constant rectangular cross-section is 133.3 mu m. Two structures (fan-shaped ...

This paper mainly presents comprehensive review on the research regarding adiabatic and diabatic gas–liquid two-phase flow patterns, bubble growth, flow pattern transitions and flow pattern maps in microchannels over the past 15 years. First, criteria for distinction of macro- and micro-channels are...
The literature survey on this issue has been categorized into adiabatic and phase change work, which has been summarized in this paper. 1.1. Adiabatic works The works of Suo and Griffith [1] were among the first studies concentrating on flow patterns in microchannels. They detected three ...
Water-butanol and water-hexane flows were visualized in ultra-shallow straight and serpentine microchannels with a cross-junction. At the inlet cross-junct
A pressure drop in microchannels was directly measured through embedded ports. The flow pattern was visualized using a high-speed camera and a long-distance microscope. A two-phase pressure drop in the microchannel was highly related to the flow pattern. Data were used to assess seven different ...
Reliable and comprehensive predictive tools for the frictional pressure drop (FPD) are of particular importance for systems involving two-phase flow condensation. However, the available models are only applicable to specific operating conditions and chan
In this work a complete set of simple and optimized correlations for flow boiling and two-phase flow conditions in microchannels were developed for prediction of the critical heat flux, flow pattern transition, heat transfer coefficient, frictional pressure drop, void fraction, slip ratio and liquid...
A new test facility was designed and constructed to investigate the two-phase flow regimes and pressure drop in mini- and micro-channels. The two-phase frictional pressure drop measurements and flow regimes experiments were performed with three different test sections, which are 3 mm, 1 mm, and...
