Abstract

The use of sensitized phosphorescence for visualization of gas phase fluid mixing and the requirements for quantitative imaging measurements are discussed. A model for estimating the molecular-mixing signal's dependence on fluid composition is developed and candidate molecular reactants are considered within the framework of the model. Experiments based on sensitized phosphorescence from both an acetonebiacetyl system and a toluene-biacetyl system show good qualitative agreement with modeled results. It is concluded that quantitative measurements using sensitized phosphorescence are feasible.
