DEVELOPMENT OF RADIAL AERODYNAMIC SWIRLERS
Keywords:
KeywordsAbstract
Experimental studies show that swirl has large-scale effects on
flowfields: jet growth. entrainment and decay (for isothermal
flows) and flame size, shape. stability and combustion intensity
(for combustion flows) are affected by the degree of swirl imparted to the flow. This degree of swirl is usually characterised by the nondimensional number representing the
ratio ofaxial flux ofswirl momentum to the axial flux of axial
momentum times the equivalent nozzle radius. This parameter.
denoted by the symbol S. is called the swirl number and has
been used extensively to designate the strength of the swirl.
This paper is to review the aerodynamics of swirling flow in
combustion system.
