Abstract

An experimental investigation was carried out to study the characteristics of concentration of a coaxial jet being tone excited and consisting of $CO_2$, and air. The concentration in a binary gas mixture was measured by using the hot-wire anemometer and flow visualization was performed by the schlieren technique. In the case of excited flow, it is found that acoustic energy is partially transferred to RMS concentration to enhance mixing.
