タイトル(掲載誌)宇宙航空研究開発機構研究開発報告 = JAXA Research and Development Report
一般注記The aim of this research is to design a bi-plane active grid to enhance turbulent flow downstream of a low-swirl burner. The active grid is a variation of the original form devised by Makita in 1991. First, adequate ranges for experimental parameters are sought using non-reacting flow. While turbulent intensity is of major interest, homogeneity, isotropy, and integral scale near the nozzle exit are also analyzed by measuring mean and turbulent velocities. In addition, a fully developed inertial subrange is demonstrated by energy spectra analysis. When premixed reacting flow is tested, a turbulent Karlovitz number higher than unity is achieved under various conditions. It indicates that the flame produced is in the thin reaction zone regime on the Peters' diagram. The measurements are implemented using both hot-wire anemometry and particle image velocimetry.
