Plug flow

Plug flow (also piston flow, Eng. Plug flow) is a term used in fluid mechanics and reaction technique and characterized an idealized form in which a liquid or gas can flow through a pipe.

Is located in a tubular reactor prior to a plug flow, so the state of the reaction mixture (such as composition, temperature, etc. ) can vary in the flow direction, for each cross section perpendicular to the flow direction, however, the state of the reaction mixture is the same. To ensure that all entering the pipe volume elements have the same residence time in the reactor. Metaphorically speaking, flows through the liquid or gas tube, as if it were a baying easily through the tube sliding stopper. This assumption is strongly simplified in so far, as a real fluid to the pipe wall more slowly than in the middle of the tube to flow and thus rows fewer individual panes of the same concentration as nested hollow cone shaped structures in a row. This effect is more pronounced with high viscosity fluids, such as in a lower viscosity.
