The numerical analysis of boiling flow instability in parallel heated channels

Flow rate distribution in parallel heated pipes

“…Instabilities in two-phase vertical flow with evaporation in parallel channels have been studied by Davies and Potter [5], Veziroglu and Lee [6], Kakaç et al [7], Aritomi et al [8,9], Fukuda and Kobori [10], Xiao et al [11], Nigmatulin et al [12], Fukuda et al [13], Kuncoro et al [14], Uehiro et al [15], Hirayama et al [16], Gao et al [17] and others. All of these works reported flow oscillations but no evidence was found on flow rate maldistribution.…”
