Combustion-based processing of polymer films and other materials often requires temporal and spatial uniformity of the combustor. We characterize the temperature and H2O mole fraction of the buoyan...

Industrial flame treatment is a common technique for oxidizing polymer films to improve adhesion and wettability. These processes are strongly influenced by flame properties such as temperature and the concentration of key combustion radicals (e.g.,

Prior research has shown that buoyant jets and plumes ‘puff’ at a frequency that depends on the balance of momentum and buoyancy fluxes at the inlet, as parametrized by the Richardson number. Experiments have revealed the existence of scaling rel

Hydroxyl radical (OH) is a key intermediate reactive species during combustion processes relevant to power production, transportation, and manufacturing. We demonstrate an OH sensor based on in situ laser absorption spectroscopy for deployment in ind

We use approximate Bayesian computation (ABC) to estimate parameters in a 3D high-temperature turbulent buoyant jet large-eddy simulation (LES). Wavelength modulation spectroscopy (WMS) provides reference temperature measurements. Parameters provide
