Abstract
This report describes the measurement of velocity profiles within and directly above a rectangular cavity with air flow across its mouth, such that standing vortices are induced in the cavity. The constant temperature hot-wire anemometer was used to determine velocity profiles at 75 feet per second free stream velocity and cavity depth over length ratios of D.75 and 1.0. Both three-dimensional and cavity geometry effects were exhibited for the vortices, and lack of periodicity in the velocities was consistently noted. All of the experimental work was conducted during April and May 1967, at the Naval Postgraduate School.
