Research output: Contribution to journalArticlepeer-review


Prior to the experimental study, the stream lines of the flow around the opening of nozzles were analyzed theoretically by conformal mapping so as to predict the most effective type of suction nozzles. Four types of nozzles of different shapes were experimentally tested using polystyrene pellets as sample granular material. The mass flow ratio and the power consumption required per unit mass of transported material were compared, and optimal nozzle proportions determined.
