Aerodynamics simulations of ground vehicles in unsteady crosswind [Elektronisk resurs]
, 2011 Ground vehicles, both on roads or on rail, are sensitive to crosswinds and the handling, travelling speeds or in some cases, safety can be affected.

Disrupted Skies: How Offshore Wind Farms Alter Flight Behavior of Breeding Seabirds. [PDF]
Ecol EvolUsing high‐resolution 1‐s tracking bursts collected every hour, we quantified within‐trajectory flight behavior of breeding Bridled Terns near offshore wind farms. Birds showed increased mean redirection and lower flight altitude when trajectories were more closely aligned with turbine directions from the colony, suggesting localized, direction ...

Influence of Marshalling Length on Aerodynamic Characteristics of Urban Emus under Crosswind [PDF]
Journal of Applied Fluid Mechanics, 2022 Urban electric multiple units (EMUs) is based on high-speed trains and metro vehicle technology. Their design speeds are generally from 160km/h to 200km/h, which mitigates the low operating speeds of metro vehicles. Traditional crosswind calculations for
