چکیده
As a part of a study of electrocoalescence of water droplets in oil, the electrically induced deformations of water-oil interfaces are studied. Cases of large deformations of the interfaces involve the strong coupling of hydrodynamics and electrostatics, in which cases numerical simulation is needed. The paper presents different numerical simulations performed using the commercial software COMSOL MULTIPHYSICSTM in cases of water-air or water-oil configurations with axial symmetry. Electrohydrodynamics problems are solved using ALE approach in deforming meshes. Comparisons are presented with the results of analytical developments, asymptotic approaches or experiments.

The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...
متن کاملStudy of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...

In this study, boundary element method was used to model sea wave propagation on a hemisphere shape under water tank and oil-water common surface oscillation in the tank. Also, kinematic and dynamic oundary conditions of free surface and common surface of oil and water were discritized by Finite difference method. There were some singularities in BEM method, which were removed by applying zonin...

متن کاملSimulation of Water Coning in Oil Reservoirs Using a Corrected IMPES Method
Implicit pressure-explicit saturation method (IMPES) is widely used in oil reservoir simulation to study the multiphase flow in porous media. This method has no complexity compared to the fully implicit method, although both of them are based on the finite difference technique. Water coning is one the most important phenomenon that affects the oil production from oil reservoirs having a water d...
