High Speed Photograpic Observation of Flow Patterns during Flow Boiling in Single Rectangular Minichannel
The present study extends the range of flow patterns observed during boiling of water in a single minichannel of height 197 μm and width 1054 μm. The calculated hydraulic diameter of the channel is 333 μm. High-speed photography is used to obtain video images of the flow field. The top covers of the channels are made of Lexan to permit visual observation, while the minichannel is machined in a ...
متن کاملDetection of Two-phase Flow Patterns in a Vertical Minichannel Using the Recurrence Quantification Analysis
The two-phase flow (water-air) occurring in square minichannel (3x3 mm) has been analysed. In the minichannel it has been observed: bubbly flow, flow of confined bubbles, flow of elongated bubbles, slug flow and semi-annular flow. The time series recorded by laser-phototransistor sensor was analysed using the recurrence quantification analysis. The two coefficients:Recurrence rate (RR) and Dete...
متن کاملTwo-Phase Flow Patterns, Pressure Drop, and Heat Transfer during Boiling in Minichannel Flow Passages of Compact Evaporators
The small hydraulic diameters employed during ow boiling in compact evaporator passages are becoming more important in diverse applications including electronics cooling and fuel cell evaporators. The high pressure drop characteristics of these passages are particularly important as they alter the ow and heat transfer, especially in parallel multichannel congurations. The pressure drop osc...
متن کاملGeothermal Two-phase Flow in Horizontal Pipes
This paper reanalysed the 255 sets of geothermal two-phase flow data of Freeston et al (1983). A new void fraction correlation is proposed in this paper. The new correlation is derived from the analysis of two-phase flow velocity distribution using the Seventh Power Law as: To predict the two-phase pressure drop, an equivalent pseudosingle-phase flow having the same boundary layer velocity dist...
