Investigation of hot streak simulation of a triple model combustor coupled with turbine guide vanes
摘要
Abstract
In order to investigate the migration laws of hot streak in the coupled system of combustor and turbine,and establish a simulation method for electrically heated swirling hot streak,this research presents construction of a triple model combustor with turbine guide vanes.Besides,a high-temperature dual-axis displacement mechanism-based temperature contact test technology is developed to obtain the temperature distribution at the combustor outlet in the coupled system under three different simulator structures.The experimental results are validated by the numerical method,and the flow field characteristics and the generation law of hot streak in the coupled system under various simulator structures are compared and analyzed.The research findings demonstrate that:1)The swirl-maintaining extension enhances the mixing effect between the mixed jets and the swirl interference mechanism in the combustor.This effectively reduces swirl dissipation and facilitates the simulation of combustion hot streak.2)As the length of the extension increases,the swirl intensity at the combustor outlet also increases,leading to changes in the distribution shape of the hot streak at the outlet.These changes influence the migration process of hot streak in the turbine guide vanes.关键词
