Experimental investigation of the effects of inlet high-swirl air preheating and dilution on kerosene flame

Applications in Energy and Combustion Science
This study investigated the effects of co-flow air swirling on the combustion of Kerosene, as relatively heavy fuel, under preheated and diluted air conditions.

The Indefinite Self-Dual Metrics and Painleve Equations

, 2002
We classify the SU(2)-invariant anti-self-dual metrics with a signature (+,+,-,-). The metrics are specified by a solution of Painleve VI, V, III or II. Moreover we show the geometric meaning of the metrics specified by each type of Painlev\'e functions ...

Laminar lifted flames in diesel engine conditions

, 2017
We present results from direct numerical simulations (DNS) of laminar lifted two-dimensional (2D) n-dodecane flames at thermochemical conditions corresponding to the Engine Combustion Network (ECN) target flame known as Spray A, which canonically represents conditions in a diesel engine.

Flame Structure and Flame–Flow Interaction in a Centrally Staged Burner Featuring a Diffusion Pilot

Aerospace
The pilot flame serves as the primary anchor for global flame stabilization in a centrally staged combustor. In engineering practice, it typically operates in the diffusion mode.

Numerical investigation of high-pressure combustion in rocket engines using Flamelet/Progress-variable models

, 2014
The present paper deals with the numerical study of high pressure LOx/H2 or LOx/hydrocarbon combustion for propulsion systems. The present research effort is driven by the continued interest in achieving low cost, reliable access to space and more ...

Forced and natural convection in laminar-jet diffusion flames [PDF]

An experimental investigation was conducted on methane, laminar-jet, diffusion flames with coaxial, forced-air flow to examine flame shapes in zero-gravity and in situations where buoyancy aids (normal-gravity flames) or hinders (inverted-gravity flames)

Investigation of Flame Stretch in Turbulent Lifted Jet Flame

Investigation of Flame Stretch in Turbulent Lifted Jet Flame
DNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analyzed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations. The mixed mode combustion is observed in instantaneous structures as in earlier studies and in averaged structure, in which the predominant mode is found to ...
