dc.description.abstractThis thesis presents an experimental study of fluid instabilities formed due to an oblique interatction of a shock wave with a cylindrical gas column seeded with glycol droplets. Two gases are injected into quiescent air to form the column. The first is sulfur hexafluoride (SF6) which generates the well-known Richtmyer-Meshkov Instability (RMI) when impulsively accelerated by a shock wave. This instability is formed due to the misalignment of the pressure and density gradients during the acceleration phase. The second is air. In this case, there is no macroscopic density gradient between the gas column and the surrounding air. Nonetheless, an instability similar to RMI develops due to the presence of the glycol droplets. Experimental studies are performed at an oblique angle of 15 degrees and a Mach number of 1.67. Experiments of this nature typically make an assumption that the cylindrical gas column is nominally two-dimensional to simplify the problem. The validity of this assumption is explored by investigating the morphology of the instabilities in multiple horizontal planes and a vertical plane. Major variations of the morphology only occur near the bounding walls, with less variation far from these walls. An investigation of the rotation of the gas column is also presented.en_US
