The determination of the heat release in technical flames is commonly done via bandpass
filtered chemiluminescence measurements in the wavelength range of OH* or CH* radicals …

In practical flames such as gas turbine combustors, spatially-integrated OH∗
chemiluminescence (CL) is frequently used as a heat release rate (HRR) indicator–which …

The in-situ and localized observation of heat release in turbulent flames is important for the
validation of computational modeling of turbulent flows with combustion. In the present work …

Chemiluminescent emissions from OH⋅, CH⋅, and C⋅ 2 and continuous emissions from
CO⋅ 2 have been measured in natural-gas-fuelled, premixed, counterflow flames operating …

The present work demonstrates the feasibility of heat release rate imaging using the laser-
induced fluorescence (LIF) of atomic hydrogen (H-atom) and formaldehyde (CH 2 O) in …

This work focuses on the use of naturally occurring optical emissions, specifically
chemiluminescence, for sensing applications in active control and health monitoring of …

Local heat release rate represents one of the most interesting experimental observables in
the study of unsteady reacting flows. The direct measure of burning or heat release rate as a …
