摘要：

Velocity measurements on axisymmetric jets are performed with both laser-Doppler anemometry (LDA) and particle image velocimetry (PIV). Two geometric configurations are investigated: circular and annular jets in still ambient fluid. The results obtained with the two measuring techniques are compared and related to the results of self-preservation theories. To describe mixing properties of the tested geometric configurations, vorticity plots are also calculated from PIV measurements: the results are useful for optimal design of efficient burners.
