Modelling of EHD gas-liquid two-phase pipe flow

In this paper, the fundamental volume averaged equations were introduced for a simulation of electrohydrodynamic gas-liquid two-phase flow, and some simple example modelling was conducted for pipe flow. For a simulation of electrohydrodynamic two-phase flow, ten equation model with five interfacial jump conditions with typical constitutive equations is introduced. New dimensionless quantities, such as gas and liquid phase Reynolds numbers, Rayleigh numbers, Prandtl numbers, Schmidt numbers, EHD numbers and two-phase interaction numbers, etc., are introduced
