N2 - 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 core occur in the flow at the nozzle exit. The distributions of the mean and pulsation velocities and pressure pulsations with varying guide vane angle are given. Self-similarity of the velocity profiles with varying Reynolds numbers is shown. The Strouhal number exhibits a nonlinear dependence on the swirl number.
