Abstract:
The initial stage of deformation of bubbles before partial discharges under the action of the electric field is studied. The bubbles are placed on the surface of the electrode. The lattice Boltzmann method is used for 3D computer simulations of dielectric liquid dynamics. The electrostatic forces acting on a dielectric fluid in an electric field are taken into account as complete Helmholtz formula that includes the electrostriction forces. After the application of the electric field, the bubbles begin to elongate in the field direction. Above the critical value of the electrical Bond number, the bubbles can detach from the surface of the electrode and float.
