Abstract
A technique is proposed for determining flow characteristics of a flow-through gas generator (GG) with the allocation of the flow rate created by gasification of a low-melting solid material in the total flow rate of gases leaving the GG. Experiments on the gasification of polypropylene samples in a flow-through GG with an approaching supersonic air flow heated in a fire heater were performed. The measured time-averaged mass flow rate of gasification products was 0.080 kg/s at the freestream Mach number M = 2.43, 0.100 kg/s at M = 2.94, and 0.050–0.020 kg/s at M = 3.81. The ratio of the total mass flow rate of the incoming air to the total output of polypropylene gasification products was 1.61–2.86.
