Full Description
Discover the cutting-edge in multiphase flows used in the process industries
In Multiphase Flows for Process Industries: Fundamentals and Applications, a team of accomplished chemical engineers delivers an insightful and complete treatment of the state-of-the-art in commonly encountered multiphase flows in the process industries. After discussing the theoretical background, experimental methods, and computational methods applicable to multiphase flows, the authors explore specific examples from the process industries.
The book covers a wide range of multiphase flows, including gas-solid fluidized beds and flows with phase change. It also provides direction on how to use current advances in the field to realize efficient and optimized processes.
Filling the gap between theory and practice, this unique reference also includes:
A thorough introduction to multiphase flows and the process industry
Practical discussions of flow regimes, lower order models and correlations, and the chronological development of mathematical models for multiphase flows
Comprehensive explorations of experimental methods for characterizing multiphase flows, including flow imaging and visualization
In-depth examinations of computational models for simulating multiphase flows
Perfect for chemical and process engineers, Multiphase Flows for Process Industries: Fundamentals and Applications is required reading for graduate and doctoral students in the engineering sciences, as well as professionals in the chemical industry.
