Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.

Formation of a fire whirl behind an L-shaped wall
Crosswind-induced fire whirl generation and development are investigated in this study, with particular emphasis on the effects of crosswind velocity, wind direction, and fuel mass loss rate on flame height and heat release behavior.

Wind Tunnel Testing on Crosswind Aerodynamic Forces Acting on Railway Vehicles
This study is devoted to measure the aerodynamic forces acting on two railway trains, one of which is a high-speed train at 300km/h maximum operation speed, and the other is a conventional train at the operating speed 100km/h. The three-dimensional train

Aerodynamic force and moment measurement for crosswind stability assessment in a compact wind tunnel
Rolling stock is sensitive to crosswind because of its large side area, so crosswind stability must be assessed when rolling stock is developed. In the European Union, aerodynamic force and moment under crosswind need to be measured in a wind tunnel ...

Numerical Investigation on Flapping Aerodynamic Performance of Dragonfly Wings in Crosswind
Numerical simulations are performed to investigate the influence of crosswind on the aerodynamic characteristics of rigid dragonfly-like flapping wings through the solution of the three-dimensional unsteady Navier-Stokes equations. The aerodynamic forces,

Flares are critical for the safe destruction of waste gases and must operate effectively over a broad range of conditions. Even at low gas flow rates, the flames created by flares are highly turbulent and exhibit significant transient behavior, yet few ...

Turbulent plumes in a uniform crosswind
Direct numerical simulation is used to investigate the integral behaviour of buoyant plumes subjected to a uniform crosswind. We find that the plume centreline is not aligned with the streamlines as is commonly assumed in integral plume models. Instead, the centreline is aligned with the total buoyancy flux, which implies that a model for the vertical ...
