Abstract:

This project is developing computational tools needed to evaluate alternate fuel combustion in a spray combustion system. The configuration chosen for final study is a subscale Referee combustor designed to investigate lean blow out (LBO) as a function of alternate fuel properties. The computational task requires development of reduced reaction kinetics for these fuels, spray fuel properties and integration into a large-eddy simulation (LES) solver. This project developed a reduced reaction kinetic model and investigated techniques for kinetics acceleration and then applied these models into an LES solver model. The Referee rig is simulated for 3 different fuels for both near blow out (NBO) and LBO. Analysis of the simulations identified critical needs for proper boundary conditions characterization and inclusion of multi-component fuel properties. Although later studies were funded by NASA (in Years 2-3), the initial study under this project demonstrated the viability of LES to study such fuel dependent kinetics in a complex gas turbine combustor.
