ABSTRACT

In an industrial research and development environment the question ‘which approach is best’ is irrelevant. Unfortunately, the ‘state of the art’ in solids flow modelling is such that, whenever possible, one will always perform experiments to get a comfortable feeling about new solids handling tools or process equipment prior to commercial application. Experimental results are backed up by modelling, using any available modelling approach, ‘quick and dirty’ if it has to be. The reliability of the design rather than the aesthetics or the general applicability and validity of a model is what counts.
