摘要
为了提高质子交换膜燃料电池系统中引射器的性能,采用CFD模拟的方法对引射器的三个关键几何参数进行了模拟分析.此外,比较了单一参数分析下最优参数组合、最优优化顺序的参数组合、正交分析得到的参数组合对引射器性能的提升.结果表明,使用正交分析得出的引射器最优参数组合分别相较其他两种性能提升了13.6%和7.5%,该研究为引射器结构参数的优化提供了一种新的思路,对引射器的设计和应用有一定的参考价值.
Abstract
In order to improve the performance of the ejector in a proton exchange membrane fuel cell system,CFD simulations were used to analyze three key geometrical parameters of the inducer.In addition,the optimal parameter combinations under single factor analysis,the parameter combinations in the optimal optimization order,and the parameter combinations obtained from orthogonal analysis were compared for the enhancement of the performance of the ejector.The results showed that the optimal combination of parameters obtained using orthogonal analysis improved the performance of the ejector by 13.6%and 7.5%respectively compared to the other two.The study provides a new idea for the optimization of the structural parameters of the ejector which is of reference value for the design and application of the ejector.
