IGNITION OF MONOHYDRIC ALCOHOLS SINGLE DROPLETS AND METHYL ESTERS OF VEGETABLE OILS
Journal Title: Физика аэродисперсных систем - Year 2014, Vol 0, Issue 51
Abstract
Evolution of monohydric alcohols (ethanol, butanol) single droplets and methyl esters of vegetable oils (RME) in a heated air within the temperature range (950 ÷ 1100К) and normal atmospheric pressure is investigated. Within the quasi-stationary approach framework, mathematical expression for droplet ignition delay time is proposed, which allows to estimate the main problem parameters influence degree on the preignition period length, with reasonable for situation analysis certainty. Obtained prognostic evaluations showed that under single droplet ignition experimental methodology conditions, ignition delay time τign of less volatile rapeseed oil methyl ester should exceed the analogous parameter ofsimilar size ethanol and butanol droplets. Calculation results are compared with mineral diesel fuel droplets ignition data.
