fluid-solid coupling elasto-dynamics generalized quasi-complementary energy
2011/9/9
The fluid-solid coupling theory, an interdisciplinary science between hydrodynamics and solid mechanics, is an important tool for response analysis and direct design of structures in naval architectur...
Application of a “Radiation-Type” Boundary Condition to the Wave, Porous Bed Problem
Radiation-Type Porous Bed Problem Boundary Condition
2009/3/7
The problem of a small-amplitude wave propagating over a flat porous bed is reanalyzed subject to the bottom boundary condition where u represents the horizontal velocity in the fluid,s represents the...
Predicting Changes in Tidal Regime：The Open Boundary Problem
Tidal Regime The Open Boundary Problem Predicting Changes
2009/3/7
Attempts to predict the impact on a tidal regime of large engineering structures are generally based on the use of a numerical model which is calibrated to reproduce the natural tidal regime and then ...
Open Ocean Modeling as an Inverse Problem：Tidal Theory
Open Ocean Modeling Inverse Problem Tidal Theory
2009/2/8
Classical models of tides in open coastal regions employ ad hoc conditions on the open boundaries instead of reliable sea level data on the coastline in order to achieve a well-posed problem. A weight...
Open Ocean Modeling as an Inverse Problem：M2 Tides in Bass Strait
Open Ocean Modeling Inverse Problem M2 Tides
2009/1/19
The solution of a linear model of barotropic M2 tides in Bass Strait is not consistent with new high quality tide gage and current meter data. This is attributed to the method used to estimate the for...
