• #### Planar 2-color time-resolved laser-induced incandescence measurements of soot in a diffusion flame ﻿

Planar two-dimensional two-colour time-resolved laser-induced incandescence (2D-2C-TiRe-LII) is employed to investigate soot formation in a standard ethylene laminar di usion ame. The time resolution of the 2D LII signal ...
• #### PLIF Measurements of Nitric Oxide and Hydroxyl Radicals Distributions in Swirled Stratified Premixed Flames ﻿

(Instituto Superior Técnico - Center for Innovation, Technology and Policy Research, Instituto Superior Técnico - Center for Innovation, Technology and Policy Research, 2016-07-04)
Environmental and economic concerns have pushed aeronautical authorities to set stringent environmental regulations on fuel consumption, noise production, and pollutant emission. Engine manufacturers are developing novel ...
• #### Quantitative Temperature Measurement of High Pressure CH$_{4}$/O$_{2}$/N$_{2}$ Laminar Flames Using Laser Induced Thermal Grating Spectroscopy (LITGS) ﻿

(Combustion Society of Japan, Combustion Society of Japan, 2016-10)
Laser diagnostics for quantitative measurements of temperature are important in high pressure and high temperature environments. In this study, Laser Induced Thermal Grating Spectroscopy (LITGS) is employed for oxygen ...
• #### Quantitative Temperature Measurement of Toluene/Air Mixture Using Laser-Induced Thermal Grating Spectroscopy ﻿

(Japan Society of Mechanical Engineers, Japan Society of Mechanical Engineers, 2016-11-01)
The ability to obtain laser based quantitative temperature measurements is particularly important in high pressure environments. In this study, quantitative temperature measurements using Laser Induced Thermal Grating ...
• #### The response of stratified swirling flames to acoustic forcing: Experiments and comparison to model ﻿

(Elsevier, 2014-07-14)
The gradient of local equivalence ratio in reacting mixtures signiﬁcantly affects the ﬂame structure and their corresponding response to acoustic velocity perturbations. We study the effect of acoustic velocity ﬂuctuations ...
• #### Scalar dissipation rate and scales in swirling turbulent premixed flames ﻿

(Elsevier, Elsevier, 2017)
Simultaneous Rayleigh scattering and OH-PLIF imaging measurements of temperature and OH were used to investigate the properties of turbulent premixed flames, including the nature of the 2D thermal structures and scalar ...
• #### Simultaneous 2D gas-phase temperature and velocity measurements by thermographic PIV with ZnO tracers ﻿

(2016-04-13)
Thermographic PIV is a recently developed technique that can achieve simultaneous 2D temperature and velocity measurements in turbulent flows/flames by seeding phosphor particles as a tracer. In essence it is a combination ...
• #### Simultaneous, two-camera, 2D gas-phase temperature and velocity measurements by thermographic particle image velocimetry with ZnO tracers ﻿

(Springer, 2017-04-01)
This work presents simultaneous 2D temperature and velocity measurements on a heated jet using two non-intensified cameras to realize thermographic PIV. In contrast to previous studies which use separate PIV cameras and ...
• #### Soot measurement in diluted methane diffusion flames by multi-pass extinction and laser-induced incandescence ﻿

(Elsevier, 2018-06-01)
Multi-pass cavity line-of-sight extinction (MPC-LOSE) and laser- induced incandescence (LII) techniques are deployed to measure the soot volume fraction in a series of nitrogen-diluted flames, which produce only ppm volume ...
• #### Technical Drawings of Cambridge Stratified Swirl Burner (SwB) ﻿

(University of Cambridge & Sandia National Laboratories, 2008)
• #### Theory and application of reverberated direct and indirect noise ﻿

(Cambridge University Press, 2017-05-01)
The generation of a temperature disturbance in a flow is accompanied by the production of acoustic waves (direct noise) and of an entropy perturbation. If this entropy perturbation is accelerated or decelerated (as is the ...
• #### A Tool for the Spectral Analysis of the Laser Doppler Anemometer Data of the Cambridge Stratified Swirl Burner ﻿

(Department of Engineering, University of Cambridge, 2012-06-08)
A series of flow fields generated by a turbulent methane/air stratified swirl burner are investigated using laser Doppler anemometer (LDA). The LDA provides flow field measurements with comparatively high temporal resolutions. ...
