Evaluating the climate impact of aviation emission scenarios towards the Paris agreement including COVID-19 effects.

Aviation is an important contributor to the global economy, satisfying society's mobility needs. It contributes to climate change through CO and non-CO effects, including contrail-cirrus and ozone formation. There is currently significant interest in policies, regulations and research aiming to reduce aviation's climate impact.

Emission Modeling of an Interturbine Burner Based on Flameless Combustion.

Since its discovery, the flameless combustion (FC) regime has been a promising alternative to reduce pollutant emissions of gas turbine engines. This combustion mode is characterized by well-distributed reaction zones, which potentially decreases temperature gradients, acoustic oscillations, and NO emissions. Its attainment within gas turbine engines has proved to be challenging because previous design attempts faced limitations related to operational range and combustion efficiency.
