Paper Abstract

Two-dimensional laser induced fluorescence of OH radicals is used to image flames in an optically accessible internal combustion engine. The two-dimensional plane is defined by forming the input XeCl excimer laser into a vertical sheet at the center of the combustion chamber. Nonconsecutive chemiluminescence and laser induced fluorescence images were observed at different delay times after the spark. The chemiluminescence images correlated well with the laser induced fluorescence images. A highly wrinkled turbulent flame in a tumble flow field as well as large cyclic variations in flame growth were observed in laser induced fluorescence images.
