Abstract : The wave equation including source terms that arise because of introduction of heat into a medium has been used as the starting point for a small-signal analysis of the Rijke phenomenon. The dependence of the onset of oscillation on means flow velocity through the tube has been Found for three different values of heater power. The results of the analysis compare favorably with experimental results when the cutoff occurs at high flow velocities. At lower flow velocities, the analysis is not satisfactory because of an instability in the mean flow. (Author)
