An Experimental Study of Flame Holding
In the present study the flame holding mechanism for lean methane- and lean propane-air flames is examined under conditions where the recirculation zone is absent.

Investigation of Fuel Geometry and Solid Fuel Combustion for Solid Fuel Ramjets
… to employ a novel fuel geometry to increase the flame-holding limits of an SFRJ. Two bench-scale solid fuel experiments were conducted to capture relevant performance metrics of five solid fuels. Performance parameters such as regression rates, surface temperature variations, molten layer …

Operation Characteristics of a Plasma Torch for Supersonic Combustion Applications with Simulated Cracked JP-7 Feedstock
… a program to examine the torch as an igniter and flame-holder for hydrocarbon-fueled scramjet engines. Previous research has shown that the plasma torch has promise as a robust igniter and flame-holder using gaseous fuels such as methane, ethylene and propylene when combined with an aeroramp to …

Simulation of Flow in a Solid Fuel Ramjet Cavity
… of the cavity, indicating that it enhances flame-holding in solid-fuel ramjets, in agreement with the experiments. The analysis of the ramjet acoustic modes shows the emergence of low frequency modes in the cavity cases, in agreement with the experiments. Using SPOD, these modes were …

Multi-scale modeling of nanosecond plasma assisted combustion
… to local plasma chemistry effects rather than flame propagation, and heat transport does not play a significant role. The nanosecond pulse discharge plasma excitation resulted in nearly simultaneous ignition over a large volume, in sharp contrast to hot-spot igniters. Next, the effect of …

Pyrolysis and Flamelet Model for Polymethyl Methacrylate in Solid Fuel Sc(ramjet) Combustors
… of pressure and high oxidizer temperatures on flamelet dynamics. The focus is on modeling the flow field with accurate chemical heat release and residence time, to better study the effects of heat flux on the solid surface and the resulting coupling. An investigation of solid fuel scramjets was …
