Anchoring of premixed jet flames in vitiated crossflow with pulsed nanosecond spark discharge

Numerical studies of nitric oxide formation in nanosecond-pulsed discharge-stabilized flames of premixed methane/air.

A simulation is developed to investigate the kinetics of nitric oxide (NO) formation in premixed methane/air combustion stabilized by nanosecond-pulsed discharges. The simulation consists of two connected parts. The first part calculates the kinetics within the discharge while considering both plasma/combustion reactions and species diffusion, advection and thermal conduction to the surrounding...

Characteristics of Turbulent Nonpremixed Jet-flames and Jet-flames in Crossflow in Normal- and Low-gravity

It is well known that buoyancy has a major influence on the flow structure of turbulent nonpremixed jet flames. For example, previous studies have shown that transitional and turbulent jet flames exhibit flame lengths that are as much as a factor of two longer in microgravity than in normal gravity. The objective of this study is to extend these previous studies by investigating both mean and f...

Multiscalar imaging in partially premixed jet flames with argon dilution

Simultaneous imaging of depolarized and polarized Rayleigh scattering combined with OH-LIF and two-photon CO-LIF provides two-dimensional measurements of mixture fraction, temperature, scalar dissipation rate, and the forward reaction rate of the reaction CO+ OH = CO2 + H in turbulent partially premixed flames. The concept of the three-scalar technique for determining the mixture fraction using...
