Resumen o descripción
Gas turbine combustors are often subjected to combustion instabilities because
of variability of operating conditions, affecting components, and altering exhaust
emissions. Herein, the analysis focuses on simulating numerically the non-premixed
combustion as unsteady flamelet combustion and detailed kinetic
mechanism. The goal is analyzing exhaust gases under unsteady inlet airflow
conditions to define operation guidelines. The numerical approach is validated
using data from the literature for nonperturbed cases. Three periodical perturbations
of different amplitude show differences with the nonperturbed case.
Besides emission of exhaust gases, the temperature field is sensitive to airflow
inlet conditions. According to the simulation results, a strong dependence of
temperature and pressure in primary and dilution zones of combustor exists on
the inlet air pressure condition. Emissions of flue gases like CO and NOx respond
to combustor thermal behavior showing high sensitivity to inlet air pressure as
well. Results indicate that moderate pressure oscillations may derive into
flashback effects.
