Abstract:
An apparatus comprising a main body adapted for use in a gas stream, the main body having a plurality of fluid passages, each fluid passage having an outlet opening on a surface of the main body, wherein fluid can flow from each outlet through each fluid passage to cover the surface as a film-like fluid, wherein:a center line of each fluid passage is inclined to a downstream side of the gas stream on the surface;an upstream inner wall of each fluid passage is inclined in an upstream direction from a predetermined inner position to a position of the upstream side of each outlet on the surface; andthe inclined upstream inner wall forms a diffusion outlet on the upstream side of each outlet;whereby the part of the fluid flowing toward the upstream side of the surface collides with the gas stream and suppresses roll up of the fluid on the surface.
