The flow of aqueous suspensions of fibres is of considerable theoretical and practical interest. It is of particular importance in the pulp and paper industry where pulp is transported through conduits in exceedingly large quantities. It also involves fundamental aspects of fluid mechanics which are concerned with such diverse phenomena as the movement of silt in rivers and estuaries and the shifting of sand dunes, and with an increasing number of important commercial applications such as pipeline transport of coal, gilsonite, pulpwood and mineral ores. More recently, two-phase systems have been involved in such sophisticated developments as the operation of nuclear reactors and complex chemical reactions in conveyed systems.
