| dc.description.abstract | El diseño de una cámara de combustión para turbinas de gas se considera tanto una ciencia como un arte. Este estudio presenta una metodología integral para el diseño de una cámara de combustión anular adaptada a las condiciones de operación de un motor CFM-56, un motor turbofán de alta relación de derivación ampliamente utilizado. El proceso de diseño implicó el cálculo de los criterios básicos y las dimensiones de la carcasa, la camisa, el difusor y el remolino, seguido de un análisis de las secciones de enfriamiento de la camisa. Se realizaron simulaciones numéricas con el software NUMECA y la herramienta de mallado HEXPRESS para predecir el comportamiento y el rendimiento de la cámara de combustión, empleando el modelo de turbulencia κ-ε y el modelo de combustión Flamelet. Se utilizó metano como combustible y se realizaron simulaciones para tres ángulos de inyección de combustible: axial, 45° y 60°. Los resultados demuestran que la cámara de combustión está correctamente dimensionada y logra una combustión completa en todas las configuraciones. La relación de presión es de 0,96, superando los criterios mínimos de diseño. Además, las emisiones de hidrocarburos no quemados son nulas, mientras que los niveles de óxidos de nitrógeno y monóxido de carbono se encuentran por debajo de los límites regulatorios. Estos hallazgos validan la metodología de diseño propuesta, garantizando un rendimiento eficiente y respetuoso con el medio ambiente de la cámara de combustión. | en_US |

| dc.description.abstractenglish | Designing a combustion chamber for gas turbines is considered both a science and an art.
This study presents a comprehensive methodology for designing an annular combustion chamber
tailored to the operating conditions of a CFM-56 engine, a widely used high bypass ratio turbofan
engine. The design process involved calculating the basic criteria and dimensions for the casing,
liner, diffuser, and swirl, followed by an analysis of the cooling sections of the liner. Numerical
simulations using NUMECA software and the HEXPRESS meshing tool were conducted to predict
the combustion chamber’s behavior and performance, employing the κ-ε turbulence model and the
Flamelet combustion model. Methane was used as the fuel, and simulations were performed for
three fuel injection angles: axial, 45◦, and 60◦. Results demonstrate that the combustion chamber
is properly dimensioned and achieves complete combustion for all configurations. The pressure
ratio is 0.96, exceeding the minimum design criteria. Additionally, the emissions of unburned
hydrocarbons are zero, while nitrogen oxides and carbon monoxide levels are below regulatory limits.
These findings validate the proposed design methodology, ensuring efficient and environmentally
compliant combustion chamber performance. | en_US |
