Mean velocity and turbulence measurements in flows of cruciform jets
Abstract
The mean flow field of air jets issuing from cruciform nozzles into still air has been observed in detail, using pitot static tubes, in the region where the flow evolves from that characterized by the nozzle cross-section to 'axisymmetric decay' far downstream. Some turbulence quantities have been measured at selected downstream locations using both hot wires and the laser velocimeter. The flow field is found to be strongly influenced by the nozzle interior design, e.g. smooth contraction vs. sharp edged orifice.
