Magnetically driven droplet break-up and vaporization: A lattice Boltzmann study

The dynamic response of magnetic liquid droplets to an externally imposed time-periodic magnetic field is analysed by means of lattice Boltzmann simulations. The dynamic load is shown to cause droplet rupture well below the static limit. In addition, evidence of magnetically driven vaporization is also reported. It is found that at appropriately high amplitude and low frequency, the magnetically driven vaporization can lead to the complete disappearance of the liquid phase. This result might have implications for the development of new vaporization procedures based on the application of oscillating magnetic fields. © 2010 IOP Publishing Ltd.
