Direct spray combustion in a tubular flame burner toward fine particle synthesis
A tubular flame burner equipped with a two-fluid nozzle for liquid precursor injection was developed and applied to the synthesis of fine particles. A tubular flame was established based on the axial spray of ethanol as a liquid fuel from the two-fluid ...

Numerical Modeling of Gaseous Partially Premixed Low-Swirl Lifted Flame at Elevated Pressure
Lifted flames have been investigated in the past years for their benefits in terms of NOx emissions reduction for gas turbine applications. In a lifted flame, the flame front stabilized on a position that is significantly detached from the nozzle exit,

Numerical Investigation of Ducted Fuel Injection Strategy for Soot Reduction in Compression Ignition Engine [PDF]
The ducted fuel injection strategy is a method that significantly reduces soot emissions in direct injection compression ignition engines. Fuel is injected into the combustion chamber through a duct enhancing the air-fuel mixture.

Flow field and interaction of lifted flames in a triple port burner
In this study, we experimentally examined a combustion field in a triple port burner. There are four flame configurations, consisting of attached flames, inner attached/outer lifted flames, inner lifted/outer attached flames, and twin lifted flames ...

Twisted absolute instability in lifted flames [PDF]
The theory of resonant modes is extended to finite length systems containing pinch points of complex axial wavenumber k0 and frequency ω0 with arbitrary ωkk0=∂2ω/∂k2. The quantity ωkk0 is shown to be an important indicator of how streamwise boundary conditions modify the local absolute mode at (k0,ω0).

A Pressurized Vitiated Co-Flow Burner and Its Preliminary Application for a Methane Lifted Flame
A new pressurized vitiated co-flow burner (PVCB) was designed and built for the investigation of lifted flame properties and was supported by a vitiated co-flow of hot combustion products from a lean H2/air flame at a controllable pressure; its ...
