Combustion regimes in sequential combustors: Flame propagation and autoignition at elevated temperature and pressure

, 2018
This numerical study investigates the combustion modes in the second stage of a sequential combustor at atmospheric and high pressure. The sequential burner (SB) features a mixing section with fuel injection into a hot vitiated crossflow.

Equivolumetric Evolution of Planar Curves

Abstract and Applied Analysis, 2014
We present the equivolumetric evolution of planar curves, which is a new type of curvature dependent evolution for a flame propagation model. This evolution reflects the nonlinear contribution of the curvature of the front to the flame propagation speed.

Study on suppression effect and mechanisms of phosphorus-containing recycling substance on flame propagation of methane/coal dust composite explosion

Meikuang Anquan
Magnesium ammonium phosphate (MgNH4PO4·6H2O) is a phosphorus-containing blockage commonly found in sewage treatment pipelines. In order to study its suppression effect on the methane/coal dust composite explosion, magnesium ammonium phosphate was ...

Visualization of Aluminum Dust Flame Propagation in a Square-Section Tube

Chemical Engineering Transactions, 2018
Metallic dust explosion is a challenging research topic. One key point of investigation is the flame propagation velocity, which can be determined experimentally by direct visualization of the explosions.

Combustion in thermonuclear supernova explosions

, 2017
Type Ia supernovae are associated with thermonuclear explosions of white dwarf stars. Combustion processes convert material in nuclear reactions and release the energy required to explode the stars.

Study on the significant effects of ignition energy and gas volume fraction on gas explosion pressure and flame propagation speed

Meikuang Anquan
The maximum flame propagation speed, the peak pressure and the pressure rise rate of gas explosion were studied under the influence of two factors of ignition energy and gas volume fraction, by using the orthogonal experimental method in a closed ...

Aerodynamic properties of turbulent combustion fields [PDF]

Flow fields involving turbulent flames in premixed gases under a variety of conditions are modeled by the use of a numerical technique based on the random vortex method to solve the Navier-Stokes equations and a flame propagation algorithm to trace the ...

Asymptotics for turbulent flame speeds of the viscous G-equation enhanced by cellular and shear flows

, 2010
G-equations are well-known front propagation models in turbulent combustion and describe the front motion law in the form of local normal velocity equal to a constant (laminar speed) plus the normal projection of fluid velocity. In level set formulation,

Reduced chemistry for butanol isomers at engine-relevant conditions

, 2017
Butanol has received significant research attention as a second-generation biofuel in the past few years. In the present study, skeletal mechanisms for four butanol isomers were generated from two widely accepted, well-validated detailed chemical kinetic
