The basic regularities of the influence of heat supply on the parameters of the flow have been elucidated with the use of analytical and numerical solutions of the quasi-one-dimensional problem on flow, through a pipe, of the gas out of a vessel with prescribed pressure and stagnation temperature to a medium with a prescribed counterpressure. It has been shown that changeover from the stationary outflow to an unsteady self-oscillatory regime of outflow is possible with increase in the thermal action on the flow. The asymptotic dependences of the flow parameter in the case of an infinitely large supplied heat have been obtained; these dependences are used in finding the scale quantities and unified generalized dependences for the period-averaged parameters of nonstationary self-oscillatory flows.
