Philadelphia CFD ConferenceApplication of MFM to a stirredchemical reactor: conclusionApril 20103D contour diagrams of productconcentration after 10 paddlerevolutions are shown forcases 1 and 2.The general patterns differ littlebut their quantitative scales do:namely from 3.2 to 2.4.So neglecting fluctuationsover-estimates reactorperformance.The explanation lies in the following calculated mixture-ratiohistograms, corresponding to a single: instant of time, vertical heightand circumferential angle, at six different radial locations.Product concentration is high only for the middle mixture ratios.
