Curvature and confinement effects for flame speed measurements in laminar spherical and cylindrical flames. [PDF]
, 2013 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 ...
