The void fraction in headers of microchannel heat exchangers
… to other traditional heat exchangers. The void fraction in the headers affects the thermal performance, refrigerant charge, and total pressure drop of MCHEs. However, due to the complex geometry of headers, measurements of void fraction in headers are challenging. A model that predicts the …

Non-intrusive two-phase flow regime identification and transport characterization in microchannels subject to uniform and non-uniform heat input
… transfer and pressure drop are a function of the local flow regime. Development of sensors that detect local void fraction and flow regimes may enable better understanding of the fundamental flow phenomena. ^ The void fraction in air-water two-phase adiabatic flow in a microchannel is measured in …

Experimental Study of Multi-phase Flow Hydrodynamics in Stirring Tanks
… inthe multi-phase flow and then measure the local void fraction. It was found that the air bubbles are carried out by the stream and dispersed to the whole bulk. However, some of the bubbles accumulate in the inactive regions, where higher void fractions were detected. The isokinetic sampling …
