Non-equilibrium formulation of void fraction in two-phase flows.

Number: 1911

Author(s) : GIANNETTI N., KIM M., YOSHIMURA H., SAITOH K.

Summary

A general variational formulation of the void fraction in dissipative two-phase flows is developed. In particular, the steady-state void fraction is extracted by the extremization of the entropy generation rate, based on a comprehensive non-equilibrium expression that introduces interfacial contributions due to surface tension between different phases and fluxes due to heat and mass transfer.
