3.1.1 Piston flow

The flow is unidirectional. In a plane perpendicular to the flow, all fluid streams move with uniform velocity, and all physical quantities are identical (concentrations, temperature, etc.), except possibly at the periphery of the fluid stream in a layer thin enough for the impact of the existence of this layer on the expression of the various axial flows to be negligible. From a chemical engineering point of view, this flow represents the transition to the properties limit of a turbulent...
