Analysis of the Airflow of Wave-Power Device By Extension of Numerical Wave Tank Code CADMAS-SURF

Abstract

 This research studies air flow of a wave power device by extension of numerical wave tank code CADMAS-SURF. To simulate air flow in the water oscillation chamber, airflow analysis program is linked to CADMAS-SURF. Energy conservation equation of the gas and Bernoulli equation for the nozzle flow are solved to estimate the pressure and air flow. The numerical results are compared with experimental results in terms of reflection characteristics of the incident waves from the air chamber, and water level and pressure variation in the air chamber, showing fair agreement overall.
