Experimental Study on Local Flame Properties of Hydrogen Added Hydrocarbon Premixed Turbulent Flames
This experimental study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u'/SL0=1.4), in order to clarify basically the influence of the addition of hydrogen to ...

Curvature and confinement effects for flame speed measurements in laminar spherical and cylindrical flames. [PDF]
This paper discusses methods used to obtain laminar flame speeds in spherical laminar premixed flames. Most recent studies express the laminar flame consumption speed as ρb/ρudR/dt, where R is the flame radius and ρb/ρu is the ratio of the burnt to the ...

Flame stretching by electric field
Abstract The paper considers the issues related to the study of the mechanisms of controlling the combustion of hydrocarbon fuels by electric fields. It is shown that influence of weak electric field on combustion in laminar mode leads to a change in the degree of flame stretching (Karlovitz number).

Temperature dependence of the Laminar burning velocity of methanol flames [PDF]
To better understand and predict the combustion behavior of methanol in engines, sound knowledge of the effect of the pressure, unburned mixture temperature, and composition on the laminar burning velocity is required.

Experimental Study of Stretched Premixed Flame Stabilized in a Flat Channel near a Heated Wall
In this work, the behavior of a lean premixed stretched flame stabilized in a flat channel near a heated wall was studied. Dependences of the flame front position on the stretch rate parameter at temperatures of the heated wall of 1000 and 1200 K and the
