Abstract
Two-phase systems have a huge potential for solving problems of removing large heat fluxes. To date, mini-channel and microchannel systems are widespread. Of particular interest are the stratified flow regime and the annular flow regime in mini- and micro- channel. It is necessary to know in detail the map of flow regimes for the realization of these flow regimes. In this paper, we present an investigation of flow regimes for a rectangular mini- channel 10 mm wide and 1.1 mm high.
Highlights
Two-phase systems in mini and micro channels have received wide application in medicine, microelectronics, power engineering, aircraft and machine building
In the field of microelectronics, boiling in microchannel is used to cool electronic components; heat exchange in heat exchangers in two-phase systems in mini and micro channels is the basis of the action of heat pipes
One of the promising ways of removing large heat fluxes from the surface of heatstressed elements of electronic devices is the use of two-phase flows in microchannels [1,2]
Summary
Two-phase systems in mini and micro channels have received wide application in medicine, microelectronics, power engineering, aircraft and machine building. In the field of microelectronics, boiling in microchannel is used to cool electronic components; heat exchange in heat exchangers in two-phase systems in mini and micro channels is the basis of the action of heat pipes. Of great interest are mini and micro channels with a rectangular cross-section that can be used in cooling systems for microchips. The hydrodynamics of two-phase flow in the minichannels height of 1 mm is investigated in [7]. Regimes in such channels significantly differ from the regimes in microchannels [8]
