Abstract

A jet-edge (JE) system is an arrangement whereby a thin blade of fluid impinges on an edge and thus, under appropriate circumstances, gives rise to tones which are called edge tones. Experimental results are presented for JE systems such as might be employed in jet-edge-resonator type whistles. Operating ranges of parameters are mapped out for various possible stages of self-oscillation. Edge tone fields are described as functions of parameters, particular emphasis being given to magnitudes and distributions-in-space of stage 1 edge tone sound fields. Examination is also made of sound fields generated by a JE system coupled to a resonator; characteristic interaction pattern is described.
