UN PROCEDIMIENTO Y UN DISPOSITIVO PARA ESTABILIZAR EL FLUJO MARGINAL EN UNA TORRE DE REFRIGERACION.

摘要

A cooling tower has a wall (1) defining a cooling air flow passage which reduces in cross-section along the direction of air flow towards a neck region (2) and then widens again. A body (3) is mounted on the wall in the neck region (2) to direct air from a central portion of the passage to a radially outer portion of the passage. In this way energy rich air from a region in the passage substantially uneffected by wall friction is injected into the energy-poor air in the boundary layer in the vicinity of the neck region. This helps to avoid boundary layer separation and thereby maintain the cooling efficiency of the tower which would otherwise be reduced.
