Research Abstract

In this study, an imaging processing technique and a four-sensor probe method for local measurements in 2- and 3-D two-phase flows respectively were developed and verified. Local measurements of two-phase flows in mini-channels (namely narrow rectangular channels) were performed and the local flow parameters such as void fraction, interfacial area concentration (IAC) and bubble diameter were obtained. Based on the database, existing two-phase frictional multiplier correlations, existing drift-flux distribution parameter and drift velocity correlations and existing IAC correlation were verified or modified. By considering the crushed bubble characteristics, an interfacial area transport equation (IATE) was derived for the narrow rectangular channels. Random collisions between bubbles and impacts of turbulent eddies with bubbles were modeled for bubble coalescence and breakup respectively. The new IATE with the sink and source terms was evaluated to be reliable by the present database.
