dc.description.abstractMass gauging of liquids in reduced and zero gravity is one of the key technologies required to enable the next step in NASA�s space exploration program. Current mass-gauging technologies rely on modeling the state of liquid in the reduced gravity conditions. Reliable modeling of liquid configuration in space application can be challenging. Recently, a model-free Spectral Mass Gauging (SMG) approach was proposed, based on probing the high-frequency asymptotics of natural acoustic modes of liquid-filled tanks. The foundation of the approach is Weyl�s Law which relates the spectral density of a resonator natural modes to the resonator�s volume. Weyl�s Law is independent of the shape of the liquid (the resonator), and thus can be used to infer the liquid volume in a reduced or zero gravity environment where the liquid configuration is unknown. An important potential application of SMG is gauging water in storage tanks in space. We report the current progress in exploring applicability of SMG to water storage tanks, both experimental and theoretical.en_US
