Modelling Effects of Micromixing on Performance of Continous Bioreactors

Effects of micromixing on performance of continuous bioreactors is investigated by determination of upper and lower boundary of substrate conversion. The bounds are evaluated on basis of limiting micromixing dynamics, i.e. as completely segregated flow and as maximum mixidness flow. Applied is probability density function of residence time (RTD) corresponding to "tank in series" model. Numerical evaluation of the bounds is obtained by solving a set of nonlinear differential equations with asymptotic split boundary conditions. Dependence of the bounds in substrate conversion as functions of Damkohler number are graphically presented
