Laminar burning velocities of Ethanol-air mixtures at elevated temperatures using the tube method

Abstract

Abstract— Experiment test for premixed laminar
combustion of ethanol-air mixtures has been conducted in a
tube technique. The laminar burning velocities of premixed
homogeneous Ethanol fuel and air mixtures are determined
over a wide range of equivalence ratio at elevated
temperatures. The experimental apparatus has been
modified for apprehension of flame behaviors at 340 K with
both ends open to the atmosphere. For each of the flame
speeds, unburned gas velocities and flame surface areas
have been measured and computed to determine burning
velocity. Repeatable and reliable experimental data are
obtained in this rig, showing good agreements with previous
data. Laminar burning velocities are increased with elevated
temperatures.
