On-orbit magnetic positive positioning of LOX: Simulation and correlation


A computational simulation is used to model magnetically induced LOX flows in reduced gravity. Simulations of magnetic positive positioning of LOX are presented and the influence of the magnetic field and background acceleration on reorientation timing is explored. A dimensionless reorientation time is sought to compliment the magnetic Bond number and Bond number as an additional predictive correlating parameter for scaling this process. Evidence is presented to support the hypothesis that magnetic fields may be an attractive option for positive positioning of cryogenic propellants in future spacecraft systems and the hypothesis that these correlating parameters are an effective means for modeling and understanding such systems. © 2003 by J.
