Studi Pengaruh Sudut Serang terhadap Kinerja Wells Turbine sebagai Wave Energy Convertr pada Oscillating Water Column

Abstract

Oscillating Water Column is a method for converting ocean wave energy into electrical energy. The mechanism of how the oscillating water column works is through the rise and fall of ocean waves, which push air into the oscillating water column, thereby rotating the turbine connected to the generator to produce an electrical current. Wave height and wave period are some of the factors influencing the power output of oscillating water column-type tidal power plants. Research was conducted to analyze turbine performance, specifically the effect of turbine angle of attack on the Coefficient of Torque (C_T) and Coefficient of Power (C_P) values. The angle of attack configuration of 12° and tip speed ratio of 2 produce the highest performance, marked by a maximum Coefficient of Torque (C_T) value of 0,361 and Coefficient of Power (C_P) value of 0,793.
