Dynamics of Actuated and Interacting Swirl Premixed Flames in Model Gas Turbine Combustors
Lean premixed combustion is preferred in gas turbines because of the reduced (NOx) emissions. However, the combustors operating in lean premixed regime could suffer from problems like flame flashback, flame blowoff and ... -
Flame Particle Tracking Analysis of Turbulence-Premixed Flame Interaction
This work describes the computational and theoretical developments made in the understanding of turbulence-premixed flame interaction, using both lean and rich H2-air mixtures, in a flow field of near-isotropic turbulence. ... -
Investigating Instability Mitigation through Flame Oscillator Synchronization
Stringent emission regulations for reducing NOx and soot emissions are driving gas turbine combustors manufacturers to adopt lean premixed combustion technology. However, the rich dynamics of turbulent, lean premixed ... -
On the Structure and Propagation of Premixed Flames in Turbulence
Turbulence interacts with flames over a multitude of lengthscales and timescales. These interactions are nonlinear and are ubiquitous, for example, in propulsion engines operating in space, air, land, and sea. ... -
Spray Interaction with Supersonic Crossflow
The flow residence time in a scramjet combustor is of the order of a millisecond (10−3s). High energy density liquid fuels are the energy carriers of choice in scramjet engines, however liquid fuels must be atomized, ... -
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ...
