Investigating the efficiency of generating electrical energy from ocean waves using multi oscillating water column devices
The multi-oscillating water column device (MOWC) is a common wave energy convertor used globally and has been the subject of study and development for many years. Wave energy is readily available and is considerably one of the most promising renewable source of energy. The MOWC device is a semi submerged chamber open to the sea. It consists of two openings. The first of which opens to the sea water and the other is in contact with the air, with the bidirectional turbine positioned in between.
My study aims to investigate the efficiency of generating electrical energy from ocean waves using multi oscillating water column devices (MOWC). The laboratory experiment will be conducted in a rectangular concrete wave flume. Four chambers representing the multi oscillating water columns will be positioned in the wave flume. A wave paddle constructed of fibre glass will create waves in the wave flume once in operation. Wave conditions will vary according to the force applied by the paddle. The arrangement of the MOWC in the wave flume will be altered during the experiment to assess its performance. The airflow and pressure will be measured & investigated within the chambers, as well as various wave parameters. Figure 1 is a representation of the experimental layout of my study.
