Abstract

Swirl flows offer an interesting field of study for
aerospace and mechanical engineers in general and for
combustion engineers in particular since it involves complex
interaction of recirculation and turbulent mixing which aid flame
stabilization in combustion systems. Swirling flow generates
rotating flows, turbulence and free jet wakes at the downstream
of swirler in combustion chamber. So there is complex
interaction between pressure gradients and fluid flow. Swirling
jets are used as a means of controlling flames in combustion
chambers. Swirling flows in both reacting and non- reacting
conditions occur in wide range of applications such as gas
turbines, marine combustor burners, chemical processing
plants, rotary kilns and spray dryers. Swirling jets are used
as a means of controlling flames in combustion chambers. This
flame stabilization can be achieved by various methods. The
most common techniques used in a gas turbine combustor is to
stabilize the flame in modern gas turbine combustors is swirl
stabilization in which a swirl velocity is imparted to the inlet air
using vane swirlers. Such flows have practical applications in
many combustion systems, such as industrial furnaces and gas
turbine combustors. Air swirlers are widely used in both tubular
& annular combustors. Swirler flow has been commonly used for
the stabilization of high-intensity combustion. Swirl can reduce
combustion lengths by producing higher rates of entrainment of
ambient fluid and fast mixing close to exit nozzle and on the
boundaries of recirculation zones in strongly swirling zones.
