Experiments have been carried out to measure the profile of the depth of a bed of sand flowing at steady state through an inclined, rotating cylinder fitted with a dam. Results are given for cylindrical and conical dams fitted at the end of the cylinder, and for cylindrical and conical internal dams, fitted halfway along the cylinder. The results are compared to the model of Saeman and of Kramers and Croockewit; the agreement is good, showing that the model is a useful predictor for flow over dams as well as for flow through cylinders without dams. The results are relevant to industrial kilns, which often contain conical brickwork dams at the discharge end and part way along the kiln.
Graphical abstractExperiments measured the bed depth profile for sand flowing through an inclined, rotating cylinder with cylindrical and conical dams at the discharge end, or cylindrical and conical internal dams halfway along the cylinder. Results for an internal dam are shown; they compare well with the model of Saeman and of Kramers and Croockewit.Figure optionsDownload full-size imageDownload as PowerPoint slide
