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.
