Turbulent multiphase flows are encountered ubiquitously in the process industry. Examples include flows within hydrocyclone separators and fluidized bed reactors. The potential for simulating these flows has primarily occurred because of advancements in computational hardware and software. However, current deficiencies in the turbulence models for mixing limit the practical utility of computational methods as an enabling technology. The proposed presentation will extend a recently developed realizable closure for the Reynolds stress of a single phase fluid to a mixture of immiscible fluids. Most significantly, the theory guarantees realizable behavior for all turbulent flows of multiphase mixtures in inertial frames and in non-inertial frames.
