Second-order wave diffraction by horizontal rectangular barriers
(2011)
A complete second-order analytical solution for the nonlinear diffraction of waves by 2-D rectangular cylinders fixed at the free surface of finite-depth waters is presented. As a sequel to a previous linear treatment of ...
An Integrated Approach to Increase Marine Transportation Safety in Harbor Areas
(Marine Technology Soc Inc, 2017)
The importance of marine transportation safety in harbors and waterways access has become a very serious governmental concern in recent years, with the holding of special conferences on major marine disasters, increasing ...
Modeling of twin-turbine systems with vertical axis tidal current turbine: Part II-torque fluctuation
(Pergamon-Elsevier Science Ltd, 2011)
We recently showed the advantage of using a numerical system to extract energy from tidal currents by developing a new twin-turbine model (Li and Calisal, 2010a). Encouraged by this result, we decided to use this model to ...
On flow fluctuation's impact on the performance of vertical axis turbines-A potential flow analysis
(Amer Inst Physics, 2017)
During the last decade, with rapidly increasing deployment of tidal current turbine prototypes in many countries, a number of failures have been reported. Several of these failures were attributed to the intensive flow ...
Three-dimensional effects and arm effects on modeling a vertical axis tidal current turbine
(Pergamon-Elsevier Science Ltd, 2010)
Three-dimensional effects in studying a vertical axis tidal current turbine are modeled using a newly developed vortex method. The effects on predicting power output and wake trajectory are analyzed in particular. The ...
An integrated model for estimating energy cost of a tidal current turbine farm
(Pergamon-Elsevier Science Ltd, 2011)
A tidal current turbine is a device for harnessing energy from tidal currents and functions in a manner similar to a wind turbine. A tidal current turbine farm consists of a group of tidal current turbines distributed in ...
Modeling of twin-turbine systems with vertical axis tidal current turbines: Part I-Power output
(Pergamon-Elsevier Science Ltd, 2010)
Recent interest in the tidal current industry has driven development of the prototype from the stand-alone turbine to the twin-turbine system. In this paper, we develop a numerical model to systematically analyze the ...
Estimating Power Output from a Tidal Current Turbine Farm with First-order Approximation of Hydrodynamic Interaction between Turbines
(Taylor & Francis Inc, 2010)
This article presents a numerical approach to estimate power output from a tidal current turbine farm with first-order approximation of hydrodynamic interactions between multiple turbines. An example study is conducted by ...
Mathematical programming basis for ship resistance reduction through the optimization of design waterline
(Springer Japan Kk, 2017)
It has been more than a decade since Calisal et al. (J Ship Res 46(3):208-213, 2002) presented their concept of wave resistance reduction by allowing an increase in the beam of a ship accompanied by smoothing the shoulders. ...
