Experiments have been carried out to study the effects of various parameters such as nozzle diameter, angle of inclination and jet velocity, on mixing time. The dependence of mixing time on the nozzle angle has been explained based on the flow patterns and concentration profiles. It has been observed that an increase in the nozzle diameter reduces the mixing time at a given level of power consumption. The energy efficiency of the jet mixers has been compared with impeller stirred tanks. Attempts have been made to identify the correlation (from previous literature) that could satisfactorily predict the experimental results obtained.
