    Abstract

    In a model of a boiler, concentration distributions of injected gas into a swirling bulk flow are determined from quantitative laser-sheet visualization. Together with LDA-measurements of velocity fields this describes the mixing process and its efficiency expressed by several measures (unmixedness, spatial scales and correlations) as function of distance downstream of point of injection. Experimental results are compared to those of numerical calculations. The visualization scheme is analysed for experimental uncertainties in terms of calibration procedure, seeding type and concentration, scale resolution and noise. The scheme allows rapid assessment of effectiveness of mixing for various nozzle configurations.
