Large-scale differential-algebraic models

The mathematical modelling of chemical processes in chemical plants, e.g. the dynamical simulation of complex chemical and physical processes in heat- and current-coupled distillation columns, leads to initial value problems for large scale systems of differential algebraic equations (DAE)... [Pg.68]

The terms lime, o(l/ )r 1(x, 0)lo1 (which, being based on Equation (6.7), represent differences between large internal energy flows), become indeterminate in the slow time scale. These terms do, however, remain finite, and constitute an additional set of algebraic (rather than differential) variables in the model of the slow dynamics. On defining z = lime, o(l/ )f (x, 0)u> the reduced-order representation of the slow dynamics becomes... [Pg.149]
