The influence of drop coalescence and breakup on the existence of multiple steady states is studied for a two-phase stirred isothermal reactor where the chemical reaction in the d̀ispersed phase obeys the rate expression − r = kC/(1 + KC) 2. The random coalescence model developed by Curl was simulated using a modified Spielman and Levenspiel Monte Carlo technique. For certain range of the coalescence rate, Damköhler number, and dimensionless feed concentration, multiple steady states have been investigated. A special case has also been considered wherein the existence of multiple steady states for finite values of the coalescence rate is contrasted to the unique steady state solution for an infinite coalescence rate.
