报告内容简介:

  Marine transport or shipping has formed the backbone of the growing international market and globalization ever since the Age of Discovery. Today, it is still undergoing continuous development to satisfy the ever-changing demands of the world trade. Due to the increase in shipping capacity and engine power in the past decade, higher flow velocities generated by larger and more powerful propellers have caused more scour-related damages to the bed and banks of harbor basins and navigation channels, when the under-keel clearance is small and the seabed and banks are not designed for such velocities. Recent research findings on the characteristics of propeller jet flow and its associated scour hole development will be presented. Highlights include new insights on the flow behaviours of a three-dimensional propeller jet in the presence of a plane boundary; the temporal and spatial developments of the unconfined/confined scour hole induced by a propeller jet; and an innovative “oblique particle image velocimetry (PIV) technique”, which allows a synchronous measurement of the flow field and the developing scour profile in a three-dimensional scour hole during the entire scouring process.
