Droplets and Sprays

The scope of the book, topics and assumptions are described. The focus of
the book is on the investigation of the underlying physics of the processes involved, development of the new physical and mathematical models of these processes, and investigation of the interaction between complex physical processes which take place in sprays. This ‘physical’ approach to droplet and spray modelling cannot replace the conventional approach, based on the direct application of computational fluid dynamics (CFD) codes, but can effectively complement it. The structure of the book broadly reflects the sequence of the processes which take place in internal combustion engines, involving the direct injection of liquid fuel. Only subcritical heating and evaporation are considered. Analysis of the interaction between droplets, collisions, coalescence, atomization, oscillations (including instabilities of evaporating droplets), size distribution and a number of other processes are beyond the scope of this book. The focus is on the models suitable or potentially suitable for implementation
in CFD codes.
