The feasibility of using ion-current sensors to monitor the combustion process in a gas turbine is investigated by developing a numerical model able to predict the field of ionic species. Different kinetic schemes describing the formation and evolution of ions were preliminary tested in simple flames and then applied to the gas turbine combustor. Significant discrepancies were found between the available kinetic schemes in literature for the present conditions.

Abstract
The feasibility of using ion-current sensors to monitor the combustion process in a gas turbine is investigated by developing a numerical model able to predict the field of ionic species. Different kinetic schemes describing the formation and evolution of ions were preliminary tested in simple flames and then applied to the gas turbine combustor. Significant discrepancies were found between the available kinetic schemes in literature for the present conditions.File in questo prodotto:
