Theory and Modeling of Dispersed Multiphase
Turbulent Reacting Flows
Theory and Modeling of Dispersed Multiphase Turbulent Reacting Flows provides
a systematic account of the fundamentals of multiphase flows, turbulent flows, and
combustion theory, as well as presenting the latest advances in the models and
theories in this field. The topics covered include: the basic equations of multiphase
turbulent reacting flows; modeling of turbulent flows; modeling of multiphase
turbulent flows; modeling of turbulent combusting flows; and numerical methods
for the simulation of multiphase turbulent reacting flows.
This book serves as a reference for teachers and researchers in engineering design,
as well as for students and research engineers in the fields of fluid dynamics,
thermal science and engineering, aeronautical, space, oil and gas, chemical,
metallurgical, petroleum, nuclear, and hydraulic engineering.
Key Features
