Some comments on estimating parameters in flow-mixing systems

Some comments on estimating parameters in flow-mixing systems 

Much of the material we have presented has relied on Laplace domain analysis in order to determine system parameters and estimate reactor 

Fitting model predictions to experimental observations can be performed in the Laplace, Fourier or time domains with optimal parameter choices often being made using weighted residuals techniques. James et al. [71] review and compare least squares, stochastic and hill-climbing methods for evaluating parameters and Froment and Bischoff [16] summarise some of the more common methods and warn that ordinary moments matching-techniques appear to be less reliable than alternative procedures. References 72 and 73 are studies of the errors associated with a selection of parameter extraction routines. 

In the introduction to this chapter, it was stated that attention would be restricted to homogeneous systems. Tracer techniques can, of course, be applied to multiphase systems and, for instance, we have already
