Flow that occurs when different elements of substrate move through the reactor at varying rates such that they are in contact with the enzyme for variable periods owing to their differing residence times in the reactor giving an opportunity for different extents of reaction to take place and for further reaction of the desired product and side-reactions to take place.  2, record 1, English, - non%2Dideal%20flow

Record number: 1, Textual support number: 1 CONT

Non-ideal flow is caused by back-mixing, convection, or the creation of stagnant regions of fluid in the reactor, for instance by channelling. Back-mixing of reactants in packed-bed reactors arises because the presence of solid particles in the column causes elements of the flowing fluid to mix, and because the different fluid elements take different routes through the reactor.  3, record 1, English, - non%2Dideal%20flow

The extent of non-ideal flow can be estimated by measuring the residence time distribution of a slug of tracer, for instance a dye injected into the inlet of the reactor, as it leaves the reactor, although sometimes allowance must be made for the hold-up of tracer molecules in porous particles.  1, record 1, English, - non%2Dideal%20flow

La représentation de l'écoulement non idéal par un modèle reposant sur des bases physiques sérieuses ne fournit pas seulement une bonne image de la distribution des temps de séjour. Le modèle postule, en outre, un certain schéma hydrodynamique qui s'approche, en le simplifiant, de l'écoulement réel. Il y a donc toutes chances, en calculant la conversion chimique prévue par le modèle, d'obtenir un résultat proche de la réalité.  1, record 1, French, - %C3%A9coulement%20non%20id%C3%A9al

In chromatography, mobile phase retention time, tm, is the time for an unretained component to elute. This time represents the minimum time a component remains on the column, which is the time all components spend in the mobile phase.  1, record 3, English, - mobile%20phase%20retention%20time

In liquid chromatography, both the mobile phase hold-up time and the retention time of the non-retained solute are the same. This is not the case in permeation chromatography.  2, record 3, English, - mobile%20phase%20retention%20time

t[indice]m apparaît ainsi comme le «temps de rétention, d'un composé non retenu» par la phase stationnaire.
