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.

• Shares new experimental data on phenomenon associated with the hydrodynamics of two-phase flow of liquid sprayed in a gas;
  
• Analyses new data and conclusions about the features of a strongly turbulent two-phase flow;
  
• Examines the mathematical model of a two-phase flow;
  
• Describes numerical simulation and calculation of hydrodynamics and interphase heat transfer in a free two-phase flow and in a cylindrical apparatus.
