A study was performed to better understand the scaling of the stoichiometric mixing length in reacting and nonreacting coaxial jets with velocity ratios greater than one and density ratios less than one. A facility was developed that incorporates a single shear coaxial injector in a laboratory rocket engine capable of ten atmospheres. Optical access allows the use of flame luminosity and laser diagnostic techniques such as Planar Laser Induced Fluorescence (PLIF).To better illustrate the timing system, a wiring schematic is presented in Fig. 4.7 and ... 77^ is the collection optics efficiency, dVc is the collection volume, a is the molecular absorption cross-section and alt;jagt; is the fluorescence quantum yield.
