✦ Synopsis

The general validity of the first-order fluid model is considered. Conditions are established for which a first-order fluid represents an acceptable approximation to the integral viscoelastic fluid from which it was derived as a Taylor series approximation. The results are applied to two flow problems: generation of flow by the application of a pressure gradient and the growth or dissolution of bubbles in viscoelastic liquids.

Optimal validation of stochastic dynamic models, e.g. by the Likelihood-Ratio test, generally requires other, overfitted models for comparison. This is avoided in a minimaxoptimal test applicable to general prediction-error models.

Matrices of transfer functions have been developed for the concentration dynamics of the rectifying and stripping sections of distillation columns. Responses of the model concentrations to fluid flow changes through the column are of first-order lag form. The parameters of the transfer functions are
