Damping effect of an external uniform magnetic field on gas bubble vibration in a viscous conductive liquid

Dynamic and heat-transfer processes accompanying the free vibrations of a gas bubble immersed in a viscous conductive liquid exposed to a uniform magnetic field are considered. Solutions to a set of equations describing bubble relaxation are obtained by numerical methods. It is shown that the magnetic field causes the fast damping of the vibration due to Joule dissipation. At the stage of vibration, the energy dissipates mainly through the Joule mechanism. At the final stage, thermal dissipation prevails.
