Tracer Technology

This volume shows how tracers can be used to follow the flow of fluids. It also develops a variety of models to represent these flows. It includes examples and problems to help enhance understanding of concepts.

The tracer method was first introduced to measure the actual flow of fluid in a vessel, and then to develop a suitable model to represent this flow. Such models are used to follow the flow of fluid in chemical reactors and other process units, in rivers and streams, and through soils and porous structures. Also, in medicine they are used to study the flow of chemicals, harmful or not, in the blood streams of animals and man.

Tracer Technology, written by Octave Levenspiel, shows how we use tracers to follow the flow of fluids and then we develop a variety of models to represent these flows. This activity is called tracer technology.

Klappentext

A vessel's behavior as a heat exchanger, absorber, reactor, or other process unit is dependent upon how fluid flows through the vessel. In early engineering, the designer would assume either plug flow or mixed flow of the fluid through the vessel. However, these assumptions were oftentimes inaccurate, sometimes being off by a volume factor of 100 or more. The result of this unreliable figure produced ineffective products in multiple reaction systems.

Written by a pioneering researcher in the field of chemical engineering, the tracer method was introduced to provide more accurate flow data. First, the tracer method measured the actual flow of fluid through a vessel. Second, it developed a suitable model to represent the flow in question. Such models are used to follow the flow of fluid in chemical reactors and other process units, like in rivers and streams, or solid and porous structures. In medicine, the tracer method is used to study the flow of chemicalsharmful and harmlessin the bloodstreams of humans and animals.

Tracer Technology Modeling the Flow of Fluids discusses how tracers are used to follow the flow of fluids, and how a variety of models are developed to represent these flows.

Octave Levenspiel is Professor Emeritus of Chemical Engineering at Oregon State University. His primary interest is chemical reaction engineering, focusing largely on applying chemical reaction kinetics and physics to the design of chemical reactors. His work has been recognized with awards that include the R.H. Wilhelm award (AIChE), the W.K. Lewis award (AIChE), and the P.V. Danckwerts award (IChemE). His previous books, including Chemical Reaction Engineering, The Chemical Reactor Omnibook, and Engineering Flow and Heat Exchange, are widely used in industry and teaching, and have been translated into 12 foreign languages.
