Magnetic retention of LOX in an accelerating environment


A computational model is utilized to simulate Magnetic Positive Propellant Positioning, (MP3), in reduced gravity. A new magnetic energy model for a dipole based on a current loop magnetic energy is developed for the public domain energy minimization code, Surface Evolver. The new model has been used to further an investigation into the feasibility of MP3 for reducing LOX boil-off during long duration missions. The equilibrium of LOX under the influence of magnetic field and background acceleration is simulated and a relationship is sought between the dimensionless parameters identified. The relationships between the energy due to a magnetic potential and a constant acceleration potential are examined for similarities across a range of volume fill fractions.
