A scientific approach to simulation of multi-phase flow dryers in presented, based on decomposing the overall system model into a material model and an equipment model. Considering the four principal types of multi-phase flow dryer, attention is mainly focused on the current ability to formulate a realistic equipment model and the problems in devising a batch drying test. Also, recent efforts to develop material models and overall system models are reviewed.

This paper reviews theoretical and experimental work on annular two-phase flow. Aspects covered include simple film theories, interfacial waves, flooding and flow reversal, droplet formation and behaviour, determination of droplet entrainment, interfacial friction, empirical methods and various applications of prediction method in annular flows.

This paper presents a comprehensive assessment of the state-of-the-art in the analysis of two-phase flow instability mechanisms. Based on a boiling water nuclear reactor (BWN) system, detailed discussion is given to illustrate the behaviour of excursive instability, pressure drop oscillations, density wave oscillations, stability margins and non-linear stability.

This paper reviews both fundamental work on the phenomena underlying industrial crystallisers and models which can describe the performance (e.g. crystal size distribution) of laboratory, pilot plant and full-scale crystallizers. Practical aspects required to consider in the design of crystallizer are also discussed.

This paper considers the motion of dilute mixtures of small solid spherical particles suspended in a viscous fluid. A comprehensive review of theoretical work for the momentum exchange between a sphere and plane wall(s), and between two or more spheres is included. The influences of fluid inertia and unsteady fluid motion are also addressed.
