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.

This work was done by David G. N. Tse of Scientific Research Associates, Inc., for Lewis Research Center.
