ENERGY GENERATION SYSTEM USING OSCILLATING WATER COLUMN CONCEPT

Abstract

the energy demand is estimated to rise considerably over the following decades. The traditional methods of energy production contribute to serious environmental problems, and all countries worldwide are exploring alternative ways to generate electricity. The ocean waves are a vital renewable energy resource that, if extensively exploited, may contribute significantly to the electrical energy supply of countries with coasts facing the sea. A wide variety of technologies has been proposed, studied, and tested at full size in actual ocean conditions. Oscillating-water-column (OWC) devices of fixed or floating are necessary wave energy devices. In this paper, the waves' energy calculation is being studied. The energy contained in the waves striking at the coast of St. Johns, Canada, is shown as an example. Further, the oscillating water column concept application to extract energy from waves is being examined. Finally, the use of Well’s turbine in such an oscillating water column is being studied. The paper summarizes the various equations used to study the oscillating water column and application of well’s turbine in such a system. MATLAB model has been used to calculate the turbine flow coefficient, turbine torque and its mean value, turbine power and its mean value. The characteristics obtained as output of the study align with the typical features of a well’s turbine.
