A jet flow from a triangular-inlet orifice can be made to oscillate or “precess” by partially confining it with a short cylindrical chamber. However, for a narrow range of chamber lengths, the jet is deflected but does not oscillate. Earlier flow-visualisation experiments with this stationary-deflected triangular jet (SDTJ) have revealed a complex flow pattern inside the chamber. The aim of thi...

The thin jet model applied by Spence to the study of the jet flap is combined with the vortex sheet model applied by Mangler and Smith to the study of leading-edge separation, to study the effect of blowing from the leading-edges of a cambered wing. The numerical techniques used to solve problems of leading-edge separation have been improved, and in the present investigation solutions have been...

Impinging jets are known as a method of achieving high convective heat transfer coefficients. One potential application of impinging jet heat transfer is the air jet cooling of a grinding process. A grinding process generates heat that must be dissipated to avoid thermal damage. To date, this has been achieved using flood cooling with a traditional coolant such as an oil and water mixture; howe...

The formation and evolution of a collisional aluminum plasma jet created by optical laser irradiation of triangular grooves with pulses of 120ps duration at an intensity of 1x10(12)W cm(-2) were studied with experiments and simulations. Series of high-contrast soft x-ray laser interferograms obtained with a 46.9nm laser mapped the plasma density evolution of an initially narrow plasma jet that ...

Near-field acoustical holography has been shown to be a useful tool for visualizing jet noise fields. It has been applied to a full-scale jet on an installed military aircraft with promising results, but the source characteristics in the extreme near field have been difficult to characterize because of the interference of acoustic reflections off the rigid reflecting plane beneath the jet. To p...
