Abstract:
Due to the paramagnetic property of liquid oxygen， the Kelvin force can be induced in liquid oxygen under non-uniform magnetic field. Based on the volume of fluid （VOF） model， the positioning effect of the force in liquid oxygen tanks is analyzed under various Bond numbers （Bo） and magnetic Bond numbers （Bom）. The results show that the magnetic field has the effect of repositioning the liquid oxygen in the tank when the gravity field is not enough or absent. Additionally， the gas-liquid interface has a periodic fluctuation during the process due to the inhomogeneous Kelvin force distribution， and more effective suppression of fluctuation can be achieved under the condition of a larger Bom. The new method of controlling gas-liquid interface of liquid oxygen tank under micro gravity condition is hoped to be developed in the future.
