20130316635 | Module, Device and Method for Providing a Fluid Curtain - A module with a flow channel for providing a fluid curtain, such as an air curtain, between different environments, comprises an inlet for introducing a fluid flow through said flow channel of the module and an outlet for introducing said fluid curtain. In addition the module comprises a honeycomb structure with plurality of parallel conduits before the outlet in order to laminarize the flow for the fluid curtain, and guiding the flow and suppressing instabilities in the flow downstream of it. Furthermore the module comprises a mechanical structure before the outlet. The mechanical structure is configured to change the velocity profile of the flow before the honeycomb structure or during the honeycomb structure so that the velocity profile of the flow after the honeycomb structure or outlet is a smooth skewed parabolic velocity profile with a peak shifted from the centre line of the symmetrical parabolic velocity profile. | 11-28-2013 |
