COMBUSTION OF LOW MELTING POINT ALKANE PARTICLES UNDER DC ELECTRIC FIELD
Journal Title: Физика аэродисперсных систем - Year 2017, Vol 0, Issue 54
Abstract
Combustion of low melting point alkanes (n-Octadecane, n-Docosane) is studied experimentally under dc electric field (EF). Nearly two-fold rise of ignition delay time is observed as a result of melting retardation under EF strength E > 60 kV/m. A burning rate constant increases within the range 10÷20 % depending on a droplet initial diameter under. Е> 82 kV/m. Droplet combustion intensification is explained by an increase of heat flux from flame luminous zone to the droplet surface as a result of flame deformation. In so way the ignition delay time of alkane particles increases and burning time decreases under dc EF.
