MEASUREMENT OF SOUND VELOCITY IN A SOLID-GAS MIXTURE

Abstract

Velocity of sound through a two-component (solid-gas) medium was measured as a function of solid particle concentration. A method was devised in which phase angle between a sound source signal and microphone signal could be measured as a function of solid particle density in the apparatus. Acoustical theory provided the necessary relationship between phase angle, density, and sound velocity. Sound velocity in the two-component medium was measured over a particle volume fraction range from 0.0001 to 0.5. The possibility of using this technique as a diagnostic instrument is discussed.
