Research on parametric design of double swirl combustion chamber

Double swirl combustion system, which is abbreviated to DSCS, is a new combustion system. For its noticeable effect on improving the fuel-air mixing process and reducing raw emissions, it has been accepted and applied widely. Double swirl combustion chamber, as one of the most important components of the DSCS, plays an important role to affect the fuel-air mixing processes and the fuel-air mixture quality which controls the combustion processes. Hence, make the further researches on the DS combustion chamber and design an optimized DS combustion chamber is very necessary and important. However, there has no reports about the researches on the configuration parameters of DS chamber have been published. Therefore, the authors make the research on parametric design of DS combustion chamber, to find out the main configuration parameters of DS chamber, and then explore how those configuration parameters affect the performance of DS chamber. In this paper, the authors make analysis on the configuration structure detailedly, and determine the crucial configuration parameters of DS chamber; and then, the authors make series of simulation researches on those parameters to reveal their effect rules, and indicate the design direction of DS chamber based on those results.
