Description
Summary:A novel technique for measuring the fluid sloshing in an opaque cylindrical tank is presented. The proposed measuring technique is fast and low cost but still maintains sufficient accuracy while offering multiple measuring points on the tank's circumference. The method expands the number of measuring points significantly compared to most reviewed methods. To measure all points, a single camera is mounted above the tank, pointing toward its center. Markers on the internal face of the tank are used to calibrate the nonlinear pixels-to-height ratio of the water level as captured by the camera. The technique can capture different sloshing flow regimes under lateral sinusoidal excitation: planar waves, swirling waves, as well as chaotic motion.
