COMPARISION CFD MODELING OF DROP -INTERFACE COALESCENCE AND EXPERIMENTAL RESULTS abstract
In the present work , separation of two immiscible liquids (sodium hydroxide and dimethyl disulfide ) was investigated and coalescence of dimethyl disulfide with mother phase was studied at interface by using numerical simulations . This phenomenon is a part of Merox unit by gravitational section in it.The volume of fluid method has been used for modeling which droplet of dispersed phase is released from nozzle toward the interface . Several experiments for measurement of coalescence time of the droplets of the dispersed phase (Dimethyl Disulfide) with the mother phase, using a high speed camera (fps1000), were performed .The comparison between experimental results and the results of modeling were compared and its shown that a compatibility between them and also the effect of several parameters including of drop diameter , continuous phase density regulated by temperature , and sodium hydroxide concentration, continuous phase to dispersed phase viscosity ratio on coalescence time were investigated .
