Numerical Simulation of Wave Interaction with Oscillating Water Column in One Dimension

Abstract

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 beginning of the canal. Conventional test cases were used in order to verify the model such as sinusoidal waves. After the model verification, the interaction of wave and OWC has been simulated. The effect of different wave conditions and also the immersion depth of the OWC’s front wall have been investigated. The numerical results were consistent with available experimental results.
