Abstracts:
Microchannel systems are actively used to cool the processor supercomputers, avionics systems, chemical and medical technologies. It is associated with a significant increase in heat and mass transfer on surfaces, and with the possibility of new regimes of flow. The aim of this work is study of two-phase gas-liquid flow in rectangular microchannel with dimension 370x217 um; we investigated the effect of the T-shaped entrance on the organization of the flow, including the distribution of gas and liquid lengths. Research methods based on the two-beam laser scanning and video, capable of measuring the velocity of slugs in the two-phase flow; determine the statistical characteristics of the two-phase flow. |
