Modelado de pilas de óxido sólido (SOFC)

Una pila de combustible es un dispositivo electroquímico que transforma directamente la energía química almacenada por un combustible en energía eléctrica y calor, con alta eficiencia y baja emisión de contaminantes. Por esto, se espera que las pilas de combustible jueguen un papel importante en la próxima generación de sistemas de producción de energía y de transporte.

Atendiendo a la temperatura de operación, las pilas de combustible se clasifican en pilas de baja temperatura (PEMFC, DMFC, AFC) y de alta temperatura (SOFC, MCFC). En la actualidad, los tipos de pila que despiertan mayor interés son: PEMFC (Proton Exchange Membrane Fuel Cell) y SOFC (Solid Oxide Fuel Cell). El GFN trabaja en modelos numéricos para la simulación de estas últimas.

Desarrollo de códigos de Fluidodinámica Computacional

El código MICSc (Momentum Interpolation Coupled Solver using PETSc; pronunciado /miksi/) es un código de investigación desarrollado como parte de la tesis de Ana Cubero.

Simulación de hogares de generación de energía eléctrica

Desde 1993, hemos desarrollado modelos de flujo, combustión, transferencia de calor y formación y reducción de contaminantes en calderas de producción de energía eléctrica de carbón, de biomasa y de residuos sólidos urbanos. Con ellos hemos simulado calderas de fuegos frontales, tangenciales, opuestos, en U y la combustión en parrilla.

Métodos de Lattice Boltzmann

Los métodos de lattice Boltzmann son una aproximación mesoscópica a la descripción del movimiento de un fluido que se basan en la ecuación de Boltzmann convenientemente discretizada en el espacio de velocidades. Esta descripción mesoscópica se contrapone a la visión macroscópica de la mecánica clásica que trata el fluido como un continuo; así como a la visión microscópica, en la que se estudia la interacción entre moléculas discretas.

El trabajo realizado se centra en el desarrollo de nuevos métodos y condiciones de contorno que permitan ampliar el campo de aplicación de la ecuación de lattice Boltzmann. Aprovechando los sólidos conocimientos de CFD del grupo, se busca establecer relaciones entre las técnicas clásicas aplicadas a la resolución de las ecuaciones de Navier-Stokes y los métodos de lattice Boltzmann.
