Abstract :
Swirling jet is used as a means of controlling flames in combustion chamber. Swirl flow offer an interesting field of study for aerospace & mechanical engineers in general and for combustion engineers in particular since it involves complex interaction of recirculation & turbulent mixing, which aid flame stabilization in combustion system. Swirling flow in both reacting & non-reacting conditions occur in wide range of application such as gas turbines, marine combustor burner, chemical processing plants, rotary kilns & spray dryers. Stabilization of flame can be achieved by various techniques. The most common techniques used in modern gas turbine combustors is swirl stabilization in which swirl velocity is imparted to inlet air using vane Swirler. Swirl can reduce combustion length by producing higher rates of entrainment of ambient fluid and fast mixing close to exit nozzle & on boundaries of recirculation zone in strongly swirling zones. Experimental studies show that swirl has large – scale effect on flow fields: jet growth, entrainment & decay and flame size, shape, stability & combustion intensity are affected by degree of swirl imparted to the flow, therefore swirling flows are commonly used to improve & control mixing process. This work present design of combustion chamber. Swirler applicable for producing CRZ (Central Recirculating Zone) to control length & stability of flame. Whole assembly design includes inlet pipes, Swirler, diffuser, expansion chamber, and tailpipe.The core objective of this study is to present the details of the experimental swirl flow. The flow through 8 blades at 45° rotating vane swirler with the effect of guide vane at 0° incidence and 0° outlet angle conditions is studied experimentally by using five-hole probe. Present work gives complete behaviour and knowledge about recirculation zone & effect of guide vanes.
