Abstract

Previous studies have determined that a magnetically susceptible fluid can be influenced by a magnetic field of sufficient strength in low gravity conditions. The use of magnetic positive positioning to manipulate magnetically susceptible fluids has potential uses in both specifying location and reducing the thermal heat leak as a means of effective positive positioning. A computational simulation is used to model the phase separation in cryogenic propellant tanks as in previous studies, while an analytic model is created to represent the magnetic field of a real permanent magnet. Previous studies have focused on the cryogenic propellant, liquid oxygen, which is attracted to regions with high magnetic field intensity. This study will focus on liquid hydrogen, which is repelled from these regions, in hopes to move the fluid away from the tank wall at points of high heat leak, such as tank supports. Using the validated computational simulation software and the validated analytic equation for the magnetic field intensity, the effectiveness of which a permanent magnet can reduce heat leak will be analyzed. Simulation results are presented to show the effectiveness of magnetic positive positioning in various states of low gravity and zero gravity.
