Simulating Magnetic Positive Positioning of Liquids in a Transient Acceleration Field

Abstract

A computational simulation of magnetic positive positioning (MP2) is used to model cryogenic propellant reorientation in reduced gravity. Previous efforts have successfully incorporated an electromagnetic field model into an axisymmetric, two-dimensional, incompressible flow model yielding accurate predictions of fluid motion induced by a magnetic field. To simulate MP 2, a three-dimensional magnetic field and magnetic force model was developed and validated as a feature of a commercially available fluid flow model. Simulation predictions obtained with the enhanced model are compared to available reduced gravity flight experiment data and include the effects of the transient acceleration environment. Evidence is presented and conclusions are drawn that support the continued use of the simulation as a viable modeling and predictive tool in the continuing study of MP2.
