CONVECTIVE HEAT TRANSFER COEFFICIENT ON A MULTIHOLED PLATE REPRESENTATIVE OF A COMBUSTION CHAMBER WALL
Аннотация
Convective heat transfer along the wall of a combustion chamber plays an important role for a gas turbine engine manufacturer.
A first scope on litterature has shown that multihole cooling was not already studied with a geometry design close to the real case. The present test bench delivers and controls the dynamic and thermal parameters of a combustion chamber and the multihole cooling was set up on a flat plate simulating the wall chamber.
Finally, we present a method for the calculation of the local convective heat transfer coefficient operating in real cases, and a modelisation of heat transfer on a multihole plate.
