An energy minimization model of magnetic positive propellant positioning (MP3)


A computational model is developed to simulate Magnetic Positive Propellant Positioning, (MP3), in reduced gravity. New models for gravitational energy, surface tension energy and magnetic energy in plane 2D and axisymmetric coordinates are developed for the public domain energy minimization code, Surface Evolver. Test cases including linear magnetic gradients, a current carrying wire and a magnetic dipole all show the new tool to be in excellent agreement with known solutions for these configurations. The new tool has been used to launch an investigation into the feasibility of MP3 for reducing LOX boil-off during long duration missions. © J.G. Marchetta by B.D. Simmons.
