On the scattering of entropy waves at sudden area expansions
Juan Guzmán-Iñigo, Dong Yang, Renaud Gaudron +1
In this work, we investigate both numerically and theoretically the sound generated by entropy waves passing through sudden area expansions. The numerical approach is based on a tr…
Acoustic absorption and generation in ducts of smoothly varying area sustaining a mean flow and a mean temperature gradient
Saikumar Reddy Yeddula, Renaud Gaudron, Aimee S. Morgans
In ducts with varying cross-sectional area and sustaining a subsonic non-isentropic mean flow, the axially varying flow conditions affect the acoustic energy balance of the system.…
The effect of hydrogen enrichment on the forced response of CH4/H2/Air laminar flames
Zhengli Lim, Jingxuan Li, Aimee S. Morgans
Hydrogen-enrichment of conventional natural gas mixtures is an actively-explored strategy for reducing pollutant emissions from combustion. This study investigates the effect of hy…
Simulation of wake bimodality behind squareback bluff-bodies using LES
F. Hesse, A. S. Morgans
A large eddy simulation (LES) study of the flow around a 1/4 scale squareback Ahmed body at is presented. The study consists of both wall-resolved (WRLES) and wall-mo…
Inlet temperature driven supercritical bifurcation of combustion instabilities in a lean premixed prevaporized combustor
X. Han, D. Laera, A. S. Morgans +4
The present article reports experimental observation and analyses of a supercritical bifurcation of combustion instabilities triggered by the air inlet temperature (Ta). The studie…
Flame interactions in a stratified swirl burner: flame stabilization, combustion instabilities and beating oscillations
X. Han, D. Laera, D. Yang +6
The present article investigates the interactions between the pilot and main flames in a novel stratified swirl burner using both experimental and numerical methods. Experiments ar…
