Abstract

The jet mixing in a downscaled, isothermal model of a rotary kiln is investigated experimentally through simultaneous particle image velocimetry and planar laser-induced fluorescence measurements. The kiln is modeled as a cylinder with three inlets in one end, two semicircular-shaped inlets for what is called the secondary fluid divided by a wall in between, called the back plate, where the burner nozzle is located. The scaling of the burner nozzle between real kiln and model and the corresponding jet flow through it is determined by the Craya–Curtet parameter. Three momentum flux ratios of the secondary fluid are investigated, and the interaction with the burner jet is scrutinized. It is found that the burner jet characteristics, its mixing with the secondary fluid and the resulting flow field surrounding the jet are dependent on the momentum flux ratio. A particular result is that stable shear layers give a more even mixing as compared to a case with shear layers subjected to a more prominent vortex shedding.
