摘要: A simple, yet representative, burner geometry is used for the investigation of highly swirling turbulent unconfined, non-premixed, flames natural gas. The configuration comprises a ceramic faced bluff-body with central fuel jet. surrounded by an annulus that delivers primary flow air. entire assembly housed in wind tunnel providing secondary co-flowing stream This hybrid bluff-body/swirl stabilizes complex not unlike those found practical combustors, amenable to modelling because its well-defined boundary conditions. Full stability characteristics including blow-off limits and comprehensive maps flame shapes are presented three different mixtures: compressed gas (CNG), CNG–air (1:2 volume) CNG–H2 (1:1 volume). It increased flow, mode may change swirl number, Sg. At low swirl, remains s...
