Analytical solutions for the acoustic field in thin annular combustion chambers with linear gradients of cross-sectional area and mean temperature
Dongbin Wang, Jiaqi Nan, Lijun Yang +2
Predictions of thermoacoustic instabilities in annular combustors are essential but difficult. Axial variations of flow and thermal parameters increase the cost of numerical simula…
A low frequency model for the aeroacoustic scattering of cylindrical tube rows in cross-flow
Aswathy Surendran, Wei Na, Charles Boakes +3
Heat exchanger tube rows can influence the thermoacoustic instability behaviour of combustion systems since they act as both acoustic scatterers and unsteady heat sinks. Therefore,…
A solution for the quasi-one-dimensional linearised Euler equations with heat transfer
Saikumar R. Yeddula, Juan Guzmán-Iñigo, Aimee S. Morgans
The unsteady response of nozzles with steady heat transfer forced by acoustic and/or entropy waves is modelled. The approach is based on the quasi-one-dimensional linearised Euler…
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…
