Acoustothermal Effects with Nonlinear Resonance Oscillations of a Gas in an Open Tube

Abstract

The results of theoretical and experimental studies of thermal secondary effects arising from nonlinear oscillations of gas in an open tube are presented. The heat flow distributions along the tube at the transition through resonance for different amplitudes of the piston displacement are obtained. It is established that the heat flow decreases from the piston to the open end. A good agreement between theoretical calculations and experimental data was obtained.
