Conference Paper
Large-Eddy Simulation (LES) of atmospheric boundary layer (ABL) is becoming an important research method for urban air-quality studies.

Wind turbines extract energy from the approaching flow field resulting in reduced wind speeds, increased turbulence and a wake downstream of the wind turbine. The wake has a multitude of negative effects on downstream wind turbines. This includes reduced efficiency and increased unsteadiness resulting in vibrations and potentially in material fatig...

Interactions between different spatial and temporal scales play a major role in determining the flow structure over the urban canopy in densely built agglomerations. The intense surface in-homogeneities result in the generation of additional terms in the turbulent transport within the urban atmospheric boundary layer (ABL), which in effect generate...

One of the greatest challenges facing transport operators and engineers today is the fast and efficient inspection, assessment, maintenance and safe operation of existing infrastructures including highways and the overall Road Infrastructure (RI) network. Due to factors such as ageing, Climate Change (CC), extreme weather conditions or other natural and manmade hazards, increased traffic demands, change in use, inadequate maintenance and deferred repairs, the transport infrastructures–including also railways, marine infrastructure, etc.- are progressively deteriorating and become more vulnerable, urgently needing inspection, assessment and repair work. The objective of this project is the reliable quantification and mapping of climate and atmospheric impacts of RIs located in Spain and in Greece. An optimal set of quantitative primary parameters and derivative impact indicators will be identified in order to quantify impacts in connection to specific categories of hazards. These could include the WMO climate extreme indicators and several hydrological and soil quality indicators. For quantifying the climate and atmospheric effects, their medium- and long-term change patterns will be assessed. A two-way coupled multi-scale numerical modelling system and technique will be utilized. This includes the advanced PALM-LES atmospheric model (https://palm.muk.uni-hannover.de/trac). High-resolution datasets of required input parameters, including land use, elevation maps, hydrological maps and 3D-site reconstruction will be collected/synthesised using the latest techniques and sources.
