As for the premixed combustion, by controlling the equivalence ratio of fuel and air, it is possible to suppress the emission of harmful substances such as NOx. However, the turbulent combustion process is very complex. Since there is unsteady flame and flow field interaction, it is very difficult to understand the combustion phenomena. To handle such a complex situation, the numerical cost may be too large. Then, by experiments, it is important to investigate turbulent combustion phenomena by laser diagnostics. In this study, we conducted a PIV/OH-PLIF simultaneous measurement of turbulent premixed flames. To focus on the effect of swirl flow on flame structure and stability, we used a cyclone-jet combustor. The extinction limit as well as CO and NOx emissions was experimentally obtained. By changing the flow condition of cyclone nozzles, we discussed the flow field with turbulence and local flame extinction.}, pages = {1714--1723}, title = {乱流燃焼場における火炎構造と火炎の安定性に及ぼす旋回流の影響}, volume = {79}, year = {2013} }
