Axisymmetric Air Jet Impinging On A Hemispherical Concave Plate, Stefan Jachna
Dissertations
This experimental study was conducted on an axisymmetric air jet impinging normally on a smooth, hemispherical, concave plate. The jet Reynolds numbers, based on bulk nozzle velocity and nozzle exit air properties, were between 14,000 and 75,000.
The impingement plate used in this work was a hemispherical surface with the radius of 94 mm.
Calibrated Pitot tubes and a micromanometer were used for pressure and velocity measurements. The Pitot tubes were mounted on precision positioning mechanisms permitting the accurate traversing of any direction in space. The test air flow rate was measured with calibrated rotometers.
