Plasma assisted combustor dynamics control
Proceedings of the Combustion Institute, 2015Abstract The primary purpose of the current research is to demonstrate and interpret the effectiveness of implementing a plasma discharge to improve combustor dynamics and flame stability. Specifically, a nano-second pulsed plasma discharge (NSPD) was applied to a premixed methane/air dump combustor for mitigation of dynamic combustion instabilities ...

Effects of Injector-Combustor Geometry on the Performance of Supersonic Combustor
Combustion Science and Technology, 1998Abstract Experimental studies were made on supersonic combustion in a two dimensional combustor using Hydrogen as fuel. A Hydrogen vitiation air heater with oxygen replenishment was used for simulating high temperature air entering the supersonic combustor.

Short Helical Combustor: Concept Study of an Innovative Gas Turbine Combustor
Volume 4A: Combustion, Fuels and Emissions, 2015An innovative design of a gas turbine annular combustor is investigated analytically and numerically. Its principal feature is the helical arrangement of the burners around the turbine shaft. Hence, a shorter combustor with lower aerodynamical losses and cooling air demand might be realized. A generic model of the combustor is developed and analyzed by

Radiative heating in scramjet combustors
31st Thermophysics Conference, 1996Currently, there is considerable interest in scramjet engines for hypersonic aircraft and missiles. This paper presents preliminary calculations of the radiative heating of the walls of scramjet combustion chambers. The analysis assumes isothermal, constant property ow elds that are representative of actual combustor ow elds.
