Combustion enclosure with cooling by transpiration
The invention relates to an enclosure containing hot gases cooled by transpiration, the enclosure comprising a porous wall and means for applying a cooling fluid to the outside face of said porous wall so as to cause a flow of cooling fluid to pass through the porous wall, by transpiration. The cool...

| description | The invention relates to an enclosure containing hot gases cooled by transpiration, the enclosure comprising a porous wall and means for applying a cooling fluid to the outside face of said porous wall so as to cause a flow of cooling fluid to pass through the porous wall, by transpiration. The cooling fluid application means comprise a plurality of cooling liquid distribution pipes regularly disposed around the porous wall and terminating tangentially on its outside face in a plurality of superposed horizontal injection levels, and feed channels crossing substantially perpendicularly through the distribution pipes, formed between each of them, and connected to cooling liquid feed means, together with calibration ducts of determined section connecting, at each of the injection levels, the vertical feed channels to the horizontal distribution pipes surrounding them so as to deliver predetermined headloss to the inside face of the porous wall, which headloss is adapted as a function of the zone to be cooled so as to optimize cooling flow rates along the porous wall. |
