OWC装置空气透平压降作用试验研究

Experimental Study on Pressure Drop of the Impulse Turbine of OWC

空气透平的压降作用及由其带来的空气流速变化,是串联2次能量转换过程、实现两转换过程耦合的核心要素。试验主要是在物理模型的基础上,对带有冲击式透平的OWC装置能量转换影响因素进行研究。试验主要考察2次能量转换耦合作用下,气室内自由水面变换、气室内压强变化、输气管内空气流速变换及三者耦合与相互作用。

The pressure drop of the impulse turbine and the change of air flowing velocity by it are the key elements, which contact the two processes of energy transform and couple them. The study based on experiments that OWC with the impulse turbine carried on the influencing factors. The research has the aim of obtaining wave height in air chamber, air pressure in chamber, and air velocity in the duct. Dealing with these data, the test gets the relationship between the above factors and finds the replacement of the impulse turbine.
