VISUALIZATION OF GRANULAR FLOW AROUND OBSTACLE

The granular flow around the obstacle, namely a cylinder, is visualized using a high-speed camera. Granular particles are driven by gravity on the inclined plate, or between two plates, and generate a shock layer via a pile that is formed ahead of the cylinder. The characteristics of granular flows are investigated by changing the size of the granular particles. The flow is gas-like using the coarse sand for the grain flow. Meanwhile, the flow is liquid-like using the mud for the grain flow.
