Experimental investigation of entropy waves during unstable combustion in the chamber of a gas turbine engine

Combustion Instability

“…Detailed coverage and the bibliography of the works, carried out in the USA in connection with LRE is contained in [2]. Various aspects of the phenomenon are described in monographs [1,7,11] and in articles [36,[38][39][40][41][42][43][44][45][46][47][48][49].…”

“…Example of the dependence of temperature in the recirculation zone on equivalence ratio when hysteresis exists[36].…”

“…Experimental investigations of propagation of entropy waves, described in Refs [35,36],. are not examined here.…”
