Spatiotemporal Surface Temperature Measurements Resolving Flame-Wall Interactions of Lean H-Air and CH-Air Flames Using Phosphor Thermometry.

Unlabelled: Spatiotemporal wall temperature (T) distributions resulting from flame-wall interactions of lean H-air and CH-air flames are measured using phosphor thermometry. Such measurements are important to understand transient heat transfer and wall heat flux associated with various flame features. This is particularly true for hydrogen, which can exhibit a range of unique flame features associated with combustion instabilities.
