A droplet in a stationary electric field
Water droplets on insulating material influence strongly the aging process of the material. The shape of the droplets signifies the state of the aging material. The present paper discusses a numerical procedure to calculate the droplet shape in an electric field generated by a constant voltage. A combined stationary solution of the droplet shape and the electric field is searched for. This lead...
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...
متن کاملElectric field mediated gene transfer.
A simple physical chemical method of transferring genes into eucaryotic cells is described. Electric impulses in the intensity range of 5-10 kV/cm with a duration of 5-10 bs were found to appreciably increase the uptake of DNA into cells. After electric field treatment, stable transformants were obtained in a system containing mouse cells deficient in thymidine kinase and a plasmid DNA harbouri...
متن کاملModelling a droplet moving in an electric field
Droplets on insulators in outdoor high-voltage equipment move and leave water films on the insulating material. These films further the development of undesirable electric currents or even flash-overs. The paper deals with the behaviour of a single droplet laying on a solid support in a strong electric field. Inside the solid support two electrodes generate the electric field. Although the expe...
متن کاملModelling a 3D Rainwater Droplet in a Strong Electric Field
Outdoor high-voltage equipment is exposed to moisture, rain and pollution. Water droplets on insulators influence negatively the material-aging process. A numerical procedure is presented which simulates the droplet behavior in a strong electric field. It consists in an iteration over an electric and a mechanical sub-problem to solve a coupled system of boundary value problems on the free domai...
