In this article, a model which examines the formation and evolution of chemiions in an aircraft engine is proposed. This model which includes chemiionisation, electron thermo-emission, electron attachment to soot particles and to neutral molecules, electron-ion and ionion recombination, ion-soot interaction, allows the determination of the ion concentration at the exit of the combustor and at t...

Experimental difficulties in following the soot formation and oxidation processes in the environment of diesel engines are recognised in the high values of the in-chamber temperature and pressure and the presence of extremely reactive intermediate species. At present, optical techniques have overwhelmed lacks typical of both local in-cylinder and totalcylinder samplings, which allow a high temp...

In the period from 2019 to 2022, joint American–Russian space experiment (SE) Flame Design (Adamant) was carried out on International Space Station (ISS). The purpose of SE study mechanisms control soot formation in a spherical diffusion flame (SDF) formed around porous sphere (PS), and radiative extinction SDF under microgravity conditions. objects this were “normal” “inverse” SDFs gaseous eth...

[1] The influence of anthropogenic aerosol (sulfate and soot) on upper tropospheric (UT) clouds through ice nucleation is studied using the NCAR Community Atmospheric Model Version 3 (CAM3) with a double moment ice microphysics treatment coupled to a global aerosol model (LLNL/UMich IMPACT). Present-day and preindustrial simulations are performed and compared for two scenarios. In the first sce...
