A report discusses experiments on the flow of water along the interior of a transparent rotating cylindrical drum, the interior of which was partitioned into five cavities by disks with central holes and outer edges attached to the cylindrical drum wall. This water-flow model was designed to provide insight into the flow in the compressor drum cavity of an advanced, high-thrust engine. In the experiments, laser Doppler velocimetry was used to measure flow velocities.
