Opis

This book advances a new view of phenomena associated with the spray of liquids from a nozzle in a gas. New results of experimental studies and numerical simulation of the hydrodynamics of an emerging two-phase flow and accompanying interphase heat and mass transfer therein are presented. The book is ideal for specialists who develop and use technologies involving the spraying of liquids in a gas, such as burning and pyrolysis of liquid hydrocarbons, granulation and drying of polymers, and dust and gas scrubbing.
