Starting in the nineteen fifties, engineers began to use chemical reactor models to understand the combustion process. The concept of modeling the combustor by a perfectly stirred reactor (PSR) followed by a plug flow reactor (PFR) was introduced by S.L. Bragg (1953). Experimental use of the concept was shown by

Stirred tanks are the most common type of batch reactor, where stirring is used to mix the ingredients initially, to maintain homogeneity during reaction, and to enhance heat transfer at a jacket wall or internal surfaces. The ideal behavior of tubular flow reactors (TFR) is plug flow, in which all nonreacting molecules have equal residence times.
