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 chemicals—harmful  and harmless—in 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.
