Occurrence-Time-Ratio Measurements on Air Entrainment in a Suction Sump
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2008 In order to get accurate measurements of air entrainment in a suction sump, we design a new and simple conductance-type electric bubble sensor, which can detect the existence of air bubbles inside a suction pipe with no disturbances by the sensor probe and with a fine spatial resolution. We focus on occurrence-time ratio γ of the air entrainment,

Analysis of Entrainment Ratio about Solar Ejector Refrigerant System
Energy Procedia, 2012 AbstractBased on the VB program, establish a simulation program about the solar ejector system performance. The characteristic of entrainment ratio has been analyzed when the HFC134a, R290 and R718 are adopted as working fluid respectively. It is found that the entrainment ratio of R290 is the biggest over the range of operating conditions, and the ...

A Study on the Design of Nozzles with a High Air Entrainment Ratio
Journal of Applied Engineering SciencesAbstract When a water jet passes through a layer of air and plunges into a pool of water, it is well known that it entrains a significant amount of air into the pool. This forms a submerged, two-phase region with a large surface area at the air-water interface. This process is called plunging water jet entrainment and aeration.
