Title: Advanced Laser Diagnostics in high-pressure spray combustion for future generation propulsion systems
 
Abstract:
In this presentation I will present a review of the work undertaken at CORIA laboratory in the industrial chair PERCEVAL focused on high-pressure spray combustion in aircraft engines. Topics covered will include quantitative kerosene fuel distribution measurements and flame structure with Planar Laser Induced Fluorescence (PLIF), temperature and concentration measurements with CPP fs CARS (Coherent anti-Stokes Raman Scattering), velocity measurements with high-speed PIV and pollutant concentration (NO, CO) with PLIF. Comparison with LES simulations will be also presented. The talk will conclude by discussing some of our ongoing work and thoughts for the future.

Title: A Portable Combustion Temperature Standard for the Calibration of Optical Diagnostic Techniques
 
Abstract:
Accurate measurement of combustion temperatures can significantly improve efficiency and reduce harmful emissions. Non-perturbing optical diagnostic techniques are capable of measuring temperatures in such environments but are often technically complex and validation is challenging, with correspondingly large uncertainties (typically 5 % -10 % of temperature). We address this by developing a portable combustion temperature standard, calibrated via the Rayleigh scattering thermometry technique, traceable to ITS-90 [1],  with a relative uncertainty (1σ)  and long-term stability of 0.5 % and 0.2 % respectively. The presentation will describe the standard flame, its calibration and measurements made using an FTIR spectrometer and hyper-spectral imager during trials as part of the recently completed EMPRESS [2] research project.

Title: In‐cylinder Optical Diagnostics
 
Presentation abstract:
In this presentation I will present a review of the last decade of optical diagnostics work undertaken in Oxford
investigating internal combustion engines. Topics covered will include quantitative fuel distribution measurements with
Planar Laser Induced Fluorescence (PLIF), temperature measurements with LIGS (Laser Induced Grating Scattering) and a
novel combination of PLIF and LIGS. The talk will conclude by discussing some of our ongoing work and thoughts for the
future.
