Experimental Study of Geometric Effect for Design of Multihole Cooling for Combustion Chamber Walls
Abstract
The increase of temperature and pressure in the gas turbines is a general trend that allows the engine performances to be increased. These higher thermodynamic cycles impose cooling systems of increasingly high performance. As a matter of fact, lean combustion, that is necessary to reduce the amount of nitrogen oxides (Nox) produced, consumes more and more air, and this air is taken mainly from the air usually reserved for cooling. The decrease of the quantity of air available for the cooling systems and the increase of the gas temperature in the combustion chamber are contradictory elements of the problem which oblige us to better control wall temperatures with a minimum air consumption.
