Purpose – An electrospinning process is a multi-phase and multi-physics process. The purpose of this paper is to numerically simulate the two-phase flow in the electrospinning process. The numerical results can offer in-depth insight into physical understanding of many complex phenomena which cannot be fully explained experimentally. Design/methodology/approach – The two-phase flow can be calculated by solving the modified Navier-Stokes equations under the influence of electric field and the interface between the two fluids has been determined by using the Volume of Fluids (VOF) method. A realizable k-e model is used to model the turbulent viscosity. The numerical results can be obtained using Computational Fluid Dynamics (CFD) techniques. Findings – The numerical simulation is a powerful tool to controlling over electrospinning parameters such as voltage, flow rate, and others. Research limitations/implications – The numerical simulation of two-phase flow model will take into account solvent evaporation and solidification of the jet, which play pivotal roles in determining the internal fiber morphology of the jet to be described here. Originality/value – This paper deals with studying numerically the two-phase flow in the electrospinning process by applying CFD techniques. And the flow is modeled by ANSYS(FLUENT) using the VOF model.

This paper presents a study on an oil-water two-phase flow model in a downhole Venturi meter by theoretical calculation, numerical simulation and experimental testing. The flow field and pressure characteristics with different flow and oil-water ratios in Venturi tube are investigated. It is found that the flow is stratified in the Venturi tube, the water phase accumulates in the tube center and the oil phase concentrates on the wall; the pressure drop is increased with flow; theoretical and numerical results are verified by experimental data.
