Typical features of fluid-particle interaction in the far field of an axisymmetric polydispersed
particle laden tube jet were measured and analysed in the present study. Measurements up
to 45 jet diameters were obtained by using a phase Doppler anemometer. The statistical
properties of four particle size classes were obtained in order to cover a wide range of
particle relaxation times. The downstream evolution of the mean longitudinal particle velocity
field aandof the particle radial and longitudinal turbulent components is first displayed. We …
