Understanding snow saltation parameterizations: lessons from theory, experiments and numerical simulations
Michael Lehning, Daniela Brito Melo, Armin Sigmund
Drifting and blowing snow are important features in polar and high mountain regions. They control the surface mass balance in windy conditions and influence sublimation of snow and ice surfaces. Despite their importance, model representations in weather an ...
2024Study of Aerodynamic Grain Entrainment in Aeolian Transport
Aeolian transport controls landform formations on Earth and other planets and crucially affects the atmospheric system. With elaborate wind tunnel measurements, we find that the aerodynamic entrainment rate follows a yet unreported exponential increase in ...
2020The Role of Reynolds Number Effect and Tip Leakage in Compressor Geometry Scaling at Low Turbulent Reynolds Numbers
Jürg Alexander Schiffmann, Markus Diehl, Christoph Schreiber
In compressor design, a convenient way to save time is to scale an existing geometry to required specifications, rather than developing a new design. The approach works well when scaling compressors of similar size at high Reynolds numbers but becomes more ...
