Combustion chamber wall

A combustion chamber for a turbomachine comprising:

• an inner wall and an outer wall that are coaxial,
• the inner wall and/or the outer wall having a cold side and a hot side and comprising at least one primary hole for enabling a first flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to feed combustion of fuel inside the combustion chamber, and a plurality of cooling holes, each having a diameter no greater than 1 mm to enable a second flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to cool the hot side of the wall,
• wherein the plurality of cooling holes is also configured to dilute combustion gas resulting from the combustion by using the flow of air penetrating to the hot side of the wall through the cooling holes.

A turbomachine comprising:

• a combustion chamber including at least one annular wall having a cold side and a hot side and including at least one primary hole for enabling a first flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to feed combustion of fuel inside the combustion chamber, and a plurality of cooling holes, each having a diameter no greater than 1 mm, to enable a second flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to cool the hot side of the wall,
• wherein the plurality of cooling holes is also configured to dilute combustion gas resulting from the combustion by using the flow of air penetrating to the hot side of the wall through the cooling holes.

A method of diluting combustion gas in a combustion chamber of a turbomachine, the combustion chamber including at least one annular wall having a cold side and a hot side, and including at least one primary hole for enabling a first flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to feed combustion of fuel inside the combustion chamber, and a plurality of cooling holes, each having a diameter no greater than 1 mm, to enable a second flow of air flowing on the cold side of the wall to penetrate to the hot side of the wall to cool the hot side of the wall, wherein a flow of air penetrating to the hot side of the wall also serves to dilute the combustion gas.
