IUTAM-BICTAM Summer School
on Violent Flows with a Free Surface
Sunday, June 2nd – Saturday, June 8th, 2019
Shanghai Jiao Tong University
Beijing International Center for Theoretical and Applied Mechanics
Part of IUTAM Summer School series
Slamming, which is the violent impact between a liquid and a solid, has been known for a long time in the ship hydrodynamics community. More recently, applications ranging from the transport of liquefied natural gas (LNG) in LNG carriers to the transformation of wave energy with oscillating wave surge converters have led to a renewed interest in the fascinating topic of slamming. The main reason is that the extreme impact pressures generated during slamming can affect the integrity of the structures. In coastal engineering, there has been a need to protect areas of water, and land, from the wave action of the sea. Protective structures such as breakwaters and sea walls need to be sufficiently robust to withstand the most violent impacts of the waves. The initial stage of impact for a body entering a fluid has been the subject of much research over the past seventy years since the independent pioneering work of von Karman and Wagner on the hydrodynamics of an alighting sea plane. At the later stage of water entry, the violent deformation of the free surface and the evolution of the cavity generate great changes of hydrodynamic load and motion of an air-to-sea body. Even some biological creatures utilize similar hydrodynamics to walk on water. Hydrodynamic flow with the violent impact is one of the most difficult topics in fluid mechanics because of the large span of spatial and temporal scales involved.
Much research effort has been devoted to understand the mechanism of slamming, wave impact and water entry/exit of a body and develop analytical solution and numerical method for the free surface hydrodynamics. One motivation for these studies is the aim to predict the impact loads on structures and the corresponding hydrodynamic flows with the violently deformed free surface. The objective of this IUTAM International Summer School is to provide an introduction to theory, method and application of hydrodynamics with the free surface. This Summer School will take place in Shanghai, China, during Summer 2019. Main topics include ship slamming, impact load, water entry/exit, breaking wave and wave impact.
The targeted audience for this Summer School will be PhD students, postdoctoral, and young researchers majoring in Fluid Mechanics, Applied Mathematics, Naval Architecture, Coastal and Ocean Engineering.
