A mathematical model of unsteady velocity sensitive thermoacoustic interactions in a heated duct (generalized Rijke tube) is developed. The model is constructed in a general way which is capable of employing any linear velocity sensitive thermoacoustic response model. A solution methodology is then constructed based on modal analysis. A number of rather general closed form solutions are presented and some of the results are used to qualitatively explain the behaviors of Rijke tubes.
