An Investigation of Behaviours of Bubble in Electric Field
The effects of an ununiform electric field on bubble behaviours such as bubble growth ,deformation and detachment are investigated experimentally.Experimental results show that the bubble elongated along the direction of the electric field.The bubble’s aspect ratio is increased with the increasing of electric field intensity and the ellipse sphere shape is more evident than without electric field,while its departure volume is decreased with that.The case is the bubble comes under the electric stress.The electric stress compressed the bubble in the equatorial direction and extened the bubble along the axial direction.The bubble behaviours influenced in the ununiform electric field is more evident than the uniform electric field.
