Collisions in Particle-laden Gas Flows

This title examines the problems involved in modelling turbulent gas flows carrying a dispersed impurity in the form of solid particles. Particular attention is directed to the consideration of various collisional processes (particle particle, particle wall, particle body) occurring in heterogeneous flows. With the use of a large file of experimental and numerical data, dimensionless criteria responsible for the presence and intensity of the indicated interactions are suggested and verified.The characteristics of turbulent heterogeneous flows in channels (pipes), as well as near streamlined bodies and in boundary layers are also considered in detail. The results of physical and mathematical modelling of particle-laden gas flows obtained in the last few years by researchers are described and analysed.The book is intended for research workers dealing with the study of gas dynamics and heat and mass transfer of multiphase flows, as well as for teachers, post-graduates and undergraduates.
