Analysis of the swirl number in a radial swirler
IV Litvinov, EU Gorelikov, DA Suslov… - AIP Conference …, 2020 - pubs.aip.org
In this study, we investigated the isothermal swirling flow at the exit of a model burner with a
radial vane swirler. Velocity profiles were measured with varying guide vane angle and
Reynolds number using a laser Doppler anemometer. Various definitions of the integral
swirl number are considered, including their correlation with the geometric swirl number and
the simple ratio of the maximum velocities in the profile is shown. It was found that at Sp>
0.6, this correlation ceases to exist and a central recirculation zone and a precessing vortex …
