## Towards Lean Combustion (TLC) for Aeroengines

The application of transported-PDF methods for the modeling of combustion and pollutant formation in aeroengines.

## Simulation of combustion and pollutant formation in lean premixed flames

By William Vicente, Sep 2000. We simulate lean, premixed, turbulent methane and propane flames using a Transported PDF combustion model implemented in the CFD code PHOENICS. Major emphasis is placed in the prediction of pollutant formation, notably CO and NOx. (In Spanish)

## Representation of chemical kinetics using Artificial Neural Networks for the simulation of turbulent reactive flows

By Javier A Blasco, Jul 2000. This thesis addresses the pioneering application of Artificial Neural Networks (ANN's) to the representation of the thermochemistry in for the simulation of turbulent combustion. The thermochemical space is automatically divided into regions using a Self-Organizing Map, and then each region is modeled with a multi-layer preceptron. (In Spanish)

## Numerical simulation of instabilities in gas-liquid interfases

By Enrique López-Pages, Feb 2000. The triggering and development of instabilities at the separating surface (interface) between two streams of liquid and a gas, downstream of dividing plates with infinitesimally thin and thick train edges are studied in this Thesis. It uses the Volume of Fluid (VOF) in order to locate and follow the liquid-gas interface, and the Continuum Surface Force method to model the effects of the surface tension force.
