Title (EN) BOUNDARY LAYER MODIFICATION IN A STACKED-PLATE APPARATUS
(FR) MODIFICATION DE COUCHE LIMITE DANS UN APPAREIL À PLAQUES EMPILÉES
Abstract:
(EN) Described is a stacked-plate apparatus having a plurality of plates stacked along an axis and having gaps between adjacent plates, each of which act as flow passageways for flow of fluid from a fluid inlet to a fluid outlet. Pairs of adjacent plates comprise one and optionally two lips, which extend axially into the flow passageway at the fluid inlet, thereby narrowing an inlet gap between the plates at the fluid inlet. The lips enhance the flow of fluid towards the fluid outlet of the flow passageway, for at least a working distance downstream thereof, as compared to a pair of adjacent plates that does not have the lips.
(FR) L'invention concerne un appareil à plaques empilées ayant plusieurs plaques empilées le long d'un axe avec des espaces entre les plaques adjacentes, chacune d'elles faisant office de canal d'écoulement pour le fluide d'une entrée de fluide à une sortie de fluide. Les paires de plaques adjacentes comprennent un et facultativement deux rebords, qui s'étendent axialement dans le canal d'écoulement au niveau de l'entrée de fluide, réduisant ainsi un espace d'entrée entre les plaques au niveau de l'entrée de fluide. Les rebords améliorent l'écoulement de fluide vers la sortie du canal d'écoulement, sur au moins une distance opérationnelle en aval de celle-ci, comparativement à une paire de plaques adjacentes n'ayant pas les rebords.
