비대칭 날개를 사용한 OWC 파력발전용 임펄스터빈의 성능예측에 대한 수치적인 연구

Abstract

The bi-directional air flow isolated in the air chamber drive the air turbine rotating by oscillating water column. Because of the compressibility of air, the air flow rates are different comparing the exhausting and inhaling process. The unsymmetric bladed impulse turbine are suggested to improve the power of converting system using the difference of airflow rate. The optimum unsymmetric ratio and angle of guide-vane have investigated using numerical method.nsymmetric bladed impulse turbine are suggested to improve the power of converting system using the difference of airflow rate.
