The design of super-cavitating propellers takes advantage of the development of air cavities on the blades? surface to reduce drag and, ultimately, increase efficiency. The mechanism of flow modification induced by the development of a cavity on the prop...

The vortices, backflow, and siltation caused by sediment-laden flow are detrimental to the safe and efficient operation of pumping stations. To explore the effects of water?sediment two-phase flow on the velocity field, vorticity field, and sediment dist...

One of the important things in a ship?s rudder design is the incidence angle of the rudder inflow to improve rudder cavitation performance. In the present study, the rudder inflow is measured by a 3-D LDV (laser Doppler velocimetry) system in a large cav...

A few decades ago, river erosion protective approaches were widely implemented, such as straightening the river course, enhancing riverbed/bank stability with layers of concrete or riprap, and increasing channel conveyance capacity (i.e., overwidening). ...

This study describes a multi-camera photogrammetric approach to measure the 3D velocity of free surface flow. The properties of the camera system and particle tracking velocimetry (PTV) algorithm were first investigated in a measurement of a laboratory o...
