应用于有机朗肯循环的喷射器理论与实验研究
Theoretical and experimental study of ejector used to organic Rankine cycle
摘要
Abstract
A organic Rankine cycle with ejector(EORC)was proposed by using ejector to the organic Rankine cycle(ORC). The ejector in the EORC induces the exhaust from the expander so as to decrease the expander backpressure and increase the pressure difference in the expander,which resulted in an increase of the power output capacity of the cycle. In order to analyze the influence of the ejector on the thermodynamic performance of the EORC,the maximum entrainment ratio and the minimum induced pressure of the ejector were analyzed based on the classical theory of ejector using R600 as the working fluid on MATLAB platform. The results showed that when the mixing pressure and the entrainment ratio of the ejector were constant,the capacity of the primary fluid to induce the second fluid in the ejector increased with increasing primary pressure. The maximum entrainment ratio and entrainment efficiency increased with the increase of the primary pressure. Based on the optimization results,the structure of ejector used to organic Rankine cycle was designed. Preliminary experiments showed that compared to ORC,the power output of the EORC increased significantly,but its systemic thermal efficiency decreased.关键词
