More recently, Mahood et al (2014aMahood et al ( , 2014bMahood et al ( , 2015aMahood et al ( , 2015b studied, experimentally and theoretically, the direct contact condensation of a swarm of two-phase bubbles in a three-phase condenser.…”

Heat transfer modelling of two-phase bubbles swarm condensing in three - phase direct - contact condenser

“…Their modelling was based on acceleration deceleration model. Continuing, Lerner and Letan [9] observed experimentally the dynamics of condensation of a single bubble in an immiscible liquid at an intermediate frequency of bubble injection. They noted that a single bubble model could be used to predict the condensation rate history within an intermediate injection frequency.…”

Experimental measurements and theoretical prediction for the volumetric heat transfer coefficient of a three-phase direct contact condenser

“…Much attention has been paid to the onecomponent direct contact condenser in the literature. On the other hand, studies of two-component direct contact condensers mainly concentrate on understanding the direct condensation phenomena through investigation of the heat transfer and the hydrodynamics of a single bubble [2][3][4][5][6][7][8][9][10][11][12][13] and a train of bubbles [14,15] The resulting lack of understanding has severely limited the practical implementation of such condensers.…”
