✦ Synopsis

A short history is given of the development of interest in residence-time distributions. Attention is concentrated on the role played in this development by Danckwerts' 1953 paper[6]. This defined the residence-time functions in the form now customarily used, and much subsequent development remains based on the approaches laid out in [6], for example, applications to flow through packed beds. Flow in pipes owes much to Taylor[12-141, but Danckwerts' work on the effect of a spread of residence times on the performance of reactors remains basic to this topic.
