The motion of vortex rings propagating horizontally in a linearly stratified medium is investigated using time-resolved planar particle imaging velocimetry. The experiments are conducted in a large water tank. Vortex rings are produced using a piston-cylinder apparatus that is driven by a stepper motor. Linear stratification is obtained using a double bucket method described in the literature. The structure and interactions of a vortex ring with a linearly stratified media are determined by the Reynolds and Froude numbers at a fixed formation ratio of the vortex ring generation. These experiments are designed to investigate the effect of varying the aforementioned parameters. The results pro..
