Three-component laser-Doppler-anemometry measurements were acquired in swirling jets with different swirl intensities and distributions. An uncertainty analysis covering the most relevant precision and bias errors was performed, and uncertainty related to the jet-center location was found to be dominant. An initial analysis of the data revealed some of the effects of swirl on hastening jet evolution. The measurements were compared with data from previous studies, and were found to be in good agreement. The range of conditions measured and the characterization of the data quality make the data set useful for guiding future experimental studies and for validating numerical approaches capable of capturing the effects of swirl on turbulence.
