摘要
Two techniques are described in this paper to determine convective transfer on a multiperforated plate; the perforations diameter can be small or large (from 1 millimeter to 1 centimeter). This study reports on heat transfer due to the air flow before it goes through the perforations. These perforations are perpendicular to the wall. For a large range of perforations spacings, an empirical relation is proposed for heat exchange at the windward surface of a perforated flat plate. (c) 2005 Elsevier SAS. All rights reserved.
