Maruhashi, J. (author), Grewe, V. (author), Frömming, Christine (author), Jöckel, Patrick (author), Dedoussi, I.C. (author)The resilient growth of air travel demands a comprehensive understanding of the climate effects from aviation emissions. The current level of knowledge of the environmental repercussions of CO2 emissions is considerably higher than that of non-CO2 emissions, which includes nitrogen oxides (NOx), sulfur oxides (SOx), other aerosols like black...abstract 2022

Kenjeres, S. (author)This work presents an application of a RANS/LES hybrid approach in simulating flows and turbulent dispersion in complex urban areas. It is demonstrated that the<br/>hybrid approach correctly captures the time-dependent behavior of the wake regions behind buildings, resulting in improvements of the total turbulent kinetic energy and, consequently...journal article 2019

Surawski, N. C. (author), Bezantakos, S (author), Barmpounis, K. (author), Dallaston, M. C. (author), Schmidt-Ott, A. (author), Biskos, G. (author)Recent advanced in the fields of nanotechnology and atmospheric sciences underline the increasing need for sizing sub-10-nm aerosol particles in a simple yet efficient way. In this article, we develop, experimentally test and model the performance of a High-Pass Electrical Mobility Filter (HP-EMF) that can be used for sizing nanoparticles...journal article 2017

Segers, A. (author)The problem of air pollution around urbanized area across Europe is strongly related to ozone. Ozone is a result of photo-chemical oxidation, and therefore an indication of the presence of pollutants. Overexposure to ozone is harmful to the health, and the concentrations are therefore measured on a regular basis to check exceedance of air...doctoral thesis 2002
