Abstract
The objective of this study was to investigate the accuracy of 2-D dilatation for identifying flame location in a turbulent reacting flow. For the experimental analysis, the experimental configuration considered was premixed fuel-air jet into a hot, vitiated crossflow. Simultaneous hydroxyl (OH) Planar Laser Induced Fluorescence (PLIF), formaldehyde (CH2O) PLIF, and (PIV) measurements were conducted to identify the experimental flame location and compute the 2-D dilatation. Numerical simulation of a 1-D premixed opposed flow flame configuration was also performed. The results from the simulations showed that dilatation correlated well with heat release. The experimental results showed that the 2-D dilatation correlated well with heat release when the flame resided away from regions of high strain-rate. When the flame was situated in regions of high strain, such as a shear layer, the 2-D dilatation was not a good indicator of heat release.
