High-speed imaging of snow saltation: wind tunnel experiments using natural snow

Michael Lehning, Daniela Brito Melo, Benjamin Andreas Walter

Drifting snow is a multi-scale process. It is composed of particles rolling and sliding along the surface, particles in saltation following short ballistic trajectories in the first 10 cm above the surface and particles in suspension at higher regions of t ...

An experimental investigation of a roof-mounted horizontal-axis wind turbine in an idealized urban environment

Fernando Porté Agel, Arslan Salim Dar, Guillem Armengol Barcos

Wind-tunnel experiments are performed to investigate the effect of minor modifications to the roof edge shape on the power performance and wake characteristics of a horizontal-axis wind turbine sited on a cube-shaped building. Three roof edge shapes are co ...

Parameterizing snow saltation: the exponential decay of the mass flux profile and its relation to the saltation dynamics

Varun Sharma, Michael Lehning, Daniela Brito Melo, Armin Sigmund

Drifting snow events lead to snow redistribution and enhance snow sublimation. Taking into account the importance of snow sublimation to the correct prediction of the surface mass balance, a general consensus has emerged within the scientific community on ...

Climatology of atmospheric boundary layer height over Switzerland

Benjamin Jérémy Laurent Heutte

Determining the height of the planetary boundary layer (PBL) is of crucial importance as it is a key parameter in air-quality modelling and weather forecasting. Continuous remote sensing measurements allow to estimate this parameter based on temperature, h ...

Effects of leading-edge separation on the vortex-induced vibration of an elongated bluff body

Guiyue Duan, Hongyu Li

Wind-tunnel experiments were conducted to investigate the effects of leading-edge separation on the vortex-induced vibration (VIV) of an elastically-supported elongated bluff body. Solid wind barriers of various heights were fixed in the leading edge to ad ...

Analysis of Pitot tube Airflow Velocity Sensor Behavior in Blockage Situations

Ata Jedari Golparvar

Several airplanes crashes throughout the past decades are linked to the failure of the airplane flow velocity sensor known as pitot device or pitot tube. The study of its behavior in blockage, either due to human errors or due to environmental factors, cou ...

Using global reanalysis data to quantify and correct airflow distortion bias in shipborne wind speed measurements

Julia Schmale, Sebastian Johannes Heinz-Josef Landwehr

At sea, wind forcing is responsible for the formation and development of surface waves and represents an important source of near-surface turbulence. Therefore, processes related to near-surface turbulence and wave breaking, such as sea spray emission and ...
