Overview
Models are useful for representing flow in real vessels, for scale up, and for diagnosing poor flow. These models apply to turbulent flow in pipes, laminar flow in very long tubes, flow in packed beds etc. An ideal pulse of tracer is introduced into a reactor and the pulse spreads as it passes through the vessel, and to characterize the spreading according to various models
Illustrate the spreading of tracer using
Dispersion model
And segregated flow model
With suitable diagram
