摘要

通过确定底物转化率的上下限，研究了微混合对连续型生物反应器性能的影响。边界是在极限微混合动力学的基础上计算的，即完全分离流动和最大混合流动。采用停留时间(RTD)的概率密度函数，对应于“槽串联”模型。通过求解一组具有渐近分裂边界条件的非线性微分方程，得到了边界的数值计算。底物转换的边界作为函数与Damkohler数的关系用图形表示。

Modelling effects of micromixing on performance of continuous bioreactors

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