Experiments have been carried out to analyse the characteristics of liquid suspensions which exhibit a non-uniform solid concentration. In order to investigate the bed behaviour, a new probe was developed and tested to measure the instantaneous concentration of solid particles. Attention is focused on slugging solid-liquid fluidized beds, where regions of low solid concentration alternate with regions of high solid concentration. The analysis of the results allowed some relevant flow characteristics (slug frequencies and slug velocities) to be recognized.
