Shockless explosion combustion - Controlled autoignition in stratified mixtures for pressure gain combustion

2021
Im Rahmen dieser Arbeit wird das zuverlässige und wiederholbare Erzeugen einer homogenen Selbstzündung innerhalb einer kontinuierlichen Strömung als neuartiges Konzept zur druckerhöhenden Verbrennung untersucht. Die druckerhöhende Verbrennung ist ein vielversprechender Ansatz zur Steigerung des Wirkungsgrades von Gasturbinen verglichen zur herko ...

Methods for Achieving a Combustion-Driven Pressure Gain in Gas Turbines

Journal of Engineering for Gas Turbines and Power, 1988
The objective of the work was to compare on both an ideal and, where possible, an actual basis the approximate performances of four types of pressure-gain combustor. Such combustors are potentially suitable for use in gas turbines in place of conventional steady-flow combustors.

Characterization of Axial Turbines for Pressure Gain Combustion

2019
Pressure gain combustion is beneficial for engine cycle efficiency, compactness, and less emissions. In this disseration, two classes of fluid expansions systems were developed to harness power from the high-speed flow delivered by the pressure gain combustor: a compact expansion system and an efficiency expansion system.

Experimental Study of Pressure Gain Combustion with Hypergolic Rocket Propellants

Journal of Propulsion and Power, 2017
This paper summarizes experimental observations of pulsed combustion occurring in a 4.5 cm diameter, nozzleless rocket combustor for pressure gain combustion applications. The combustor featured an impinging jet injector and operated on high-concentration hydrogen peroxide with a catalyst-laced hydrocarbon-based fuel.

Pressure-Gain Combustion: Part II—Experimental and Model Results

Journal of Engineering for Gas Turbines and Power, 1996
An experimental investigation of aerovalve pulse combustion is presented. The experimental measurements compare favorably with model predictions from a control volume analysis of the pulse combustor. Particular emphasis is placed on the mean pressure differences through the combustor as an indicator of the so-called pressure gain performance.

Recent Developments in the Research on Pressure-Gain Combustion Devices

2019
Unlike conventional engines based on the Brayton cycle, detonation-based combustion devices can result in a net pressure gain, in addition to the temperature increase during the combustion process. Pulse detonation engines (PDEs) have been studied for more than seventy years.
