Abstract
An attempt to use a simplified vortex model to study jet noise is repo rted. Special considerations are given to relate the vortex ring prope rties with jet how parameters, such as jet velocity, nozzle radius, an d jet-structure Strouhal number. Results show good agreement with exis ting low-Mach-number turbulence sound theories and experimental observ ations of an initially laminar jet. They also give new insight into so me well-established jet noise phenomena.
