Improved turbulent lift momentum closure for multiphase computational fluid dynamics

More efficient boiling heat transfer systems in nuclear reactors can help lower the costs of a large, low carbon energy source. Multiphase computational fluid dynamics (M-CFD) can be utilized in the design of these systems, but requires additional modeling for interphase transfer of mass, momentum, and energy [1]. Within the momentum transfer between phases, the interfacial lift force strongly affects the lateral migration of the gas phase in bubbly flow, which strongly impacts the predictions of pressure drop and heat transfer [2]. Recent work from Sugrue has proposed an improved physical representation of the turbulent lift force utilizing a combination of direct numerical simulation (DNS) data and a numerical optimization of the lift coefficient using experimental data [3].
