Abstract: An experimental study was conducted on a chemically reacting liquid round free jet. The Laser Induced Fluorescence (LIF) technique was adopted to evaluate the mixing suppression of the jet into liquid streams. The jet profiles were quantitatively evaluated for both the upstream region near the transition point and the downstream region far away from the transition point, and comparisons were conducted between the reacting and the non-reacting jet cases. In the downstream region, the jet profiles for the two cases were found to be quite different. It was concluded that the occurrence of a chemical reaction affects the momentum diffusion of the jet in the downstream region, which results in these differences.
