Abstract : In 1859, Rijke obtained a heat-driven sound from a round tube held in a vertical position by placing a grid one-fourth of the way from the bottom of a 0.8 meter long tube and heating the grid to a red heat with a gas flame. These heat driven oscillations in the simple tube are now recognized to be caused by the same mechanism which results in various types of combustion instabilities. In their mild form these instabilities are undesirable and can become quite destructive in their more severe forms. Better known examples of these instabilities occur as rumble and afterburner screech in jet engines and in rocket engine instabilities. The purpose of this study was to construct an experimental Rijke tube apparatus and investigate the effect of the parameters, velocity, heat power, and wall temperature, with primary emphasis on wall temperature.
