Contact between phases is a very common operation in chemical and process engineering. This chapter concerns the contact between multiple solid particles and a continuous gas phase. It draws upon the content of Chapter 4, on the interaction between single particles and a fluid.
Multiphase systems containing particles present inherent difficulties which do not exist in simple multiphase systems, particularly ...
