Article history: Received 26.04.2012. Received in revised form 17.07.2012. Accepted 17.07.2012. Sea wave energy is one of the high potential renewable energy sources. The Wells turbine as the main part of Oscillating Water Column energy plant is analyzed in this paper. The Wells turbine uses air flow produced by the pressure change inside the oscillating water column. Efficient energy transform...
A numerical model has been introduced to simulate wave interaction with oscillating water column (OWC) in two dimensional vertical plane. Two-dimensional Navier-stokes equations have been used. To track free surface, Volume of fluid method has been employed. Also a porous wall is situated at the beginning of the canal to absorb the reflected waves. It’s valuable to mention that the Poisson equa...
Oscillating water column (OWC) is one of the wave energy converting devices available. In this article, a numerical model has been introduced to simulate wave interaction with OWC in one dimensional plane. Mild slope equations have been used in one dimension. The pressure and water elevation inside OWC have been calculated using an iterative method. Also an absorbing boundary is used at the beg...
The hydrodynamic performance of a floating cylindrical oscillating water column (OWC) wave energy converter is investigated experimentally and numerically. physical experiment carried out in flume at Dalian University Technology. OWC device constrained by springs only moves vertically. A second-order time-domain Higher-Order Boundary Element Method, based on the perturbation expansion technique...
