... numerical simulation of primitive hydrodynamic equations is becoming now an available alternative to solving kinetic equations for wind waves in the Ocean. In contrast to the kinetic theory, the dynamic equations do not use the assumption of independent random wave phases and of a slow evolution, thus...

... Abstract A two-dimensional wedge entering water is studied based on two-phase SPH (Smoothed Particle Hydrodynamics) method. We have designed wedges with different deadrise angle to study the cavity evolution and gas flow in the cavity. The liquid phase and gas phase are used by weak...

... ABSTRACT: The Hechangzhou Braided Channel in Zhenyang (Zhenjiang-Yangzhou) Reach is one of the severely changing sections in the lower reaches of Yangtze River. To effectively forecast the evolution trend of this reach and prevent disaster, this paper is mainly based on the concepts...

... and the evolution of the cavity running with the body. Considering a water entering wedge as a model for studying on slamming, the first complete solution was obtained by Dobrovol'skaya(1969) for a two-dimensional wedge based on potential flow theory and, then, Zhao and Faltinsen(1993) studied theoretically...

... field in the oceanic coastal zone many times; see for instance (Huntley and Bowen 1973; Bryan Hows and Bowen 1998). Edge waves are often considered as the major factor of the long-term evolution of irregular coastal line, forming the rhythmic crescentic bars (Bowen and Inman 1971; Komar 1998). (Komar...
