Wave Rotors Performance Enhancement
2014/11/13
Significant performance enhancement of microturbines is predicted by implementing various wave-rotor-topping cycles. Five different advantageous cases are considered for implementation of a four-port ...
Longitudinally Stratified Combustion in Wave Rotors
Longitudinally Stratified Combustion Wave Rotors
2014/11/13
A wave rotor may be used as a pressure-gain combustor, effecting wave compression and expansion, and intermittent confined combustion, to enhance gas-turbine engine performance. It will be more compac...
Assessment of Combustion Modes for Internal Combustion Wave Rotors
Combustion Modes Internal Combustion Wave Rotors
2014/11/13
Combustion within the channels of a wave rotor is examined as a means of obtaining pressure gain during heat addition in a gas turbine engine. Three modes of combustion are assessed: premixed autoigni...
