Abstract Details

2006, MS, University of Cincinnati, Engineering : Aerospace Engineering.
An investigation into the dynamics of liquid in an enclosed container experiencing low frequency, small amplitude roll oscillations was performed. Previous research suggests that under dynamic conditions can decrease the lower flammability limit; however characterization of the fluid dynamics in these tests was not performed. This study examined these dynamics by utilizing a motion simulator and a 2.1 m3 capacity rectangular tank. Water depths of 0.265 m, 0.371 m, and 0.530 m were examined. The tank experienced a two dimensional roll oscillation at frequencies between 0.25 Hz to 0.45 Hz at oscillation amplitudes of 2.42°, 3.50°, and 4.71°. The formation of a hydraulic jump was observed at tank oscillations near the resonance frequency of the liquid volume and the formation of these jumps occurred at the frequency, but out of phase, of the driven tank oscillation. At lower frequencies, wave/wave interactions were observed that caused spray formation in specific locations of the tank ullage.
