OP-II-3

OP-I-25effect of bubble break-up would be insignificant. Just such conditions wereimplemented in numerous and detailed experiments performed for the paper [2].The results of experiments were compared with Direct Computer Simulation data,obtained using different generally accepted coalescence models and a novel bubblecoalescence model based on critical Reynolds number [3].References[1].
