Abstract

Abstract

In order to characterize the explosion of the gasoline vapor/air mixture, we introduced the unstretched laminar burning velocity of premixed gasoline vapor/air flame to the research of the mixture. The unstretched laminar burning velocity was experimentally studied and compared with those of two mixture gases consisting of such major compositions of gasoline as isooctane and n-heptane, respectively. The results show that the unstretched laminar burning velocity of the prepared gasoline vapor/air mixture is lower than those of the isooctane/air mixture gas and the n-heptane/air misture gas, but it takes on a similar tendency to change with the equivalence ratio, i.e. the unstretched laminar burning velocity firstly increases and then decreases with the increase of the equivalence ratio, and the maximum value can be obtained at the equivalence ratio of 1.
