Railway Aerodynamics
Aerodynamics is a key factor in the design and operation of trains. A reduction in wind resistance will improve fuel economy, and may permit increased speeds. The reaction of rolling stock to turbulent cross-winds is crucial in determining train overturning risk, and maximising operating speeds. BMT Fluid Mechanics provides a comprehensive range of consultancy services to support rolling stock and track design, and to help frame operating procedures in high winds. View »

Airports and heliports
The safety and operability of airports and heliports can be influenced by turbulence and wind shear, and by proximity to sources of hot gases such as power stations. Turbulence and wind shear is caused primarily by the local topography such as mountainous or hilly terrain and by proximity to large man-made structures or buildings (e.g. terminal buildings and aircraft hangers). The disruption to the natural wind flows can have a serious effect on the performance and controllability of fixed wing aircraft and helicopters, and can result in operational restrictions being placed on an airport or heliport under certain wind conditions. The presence of hot gases is also a potential hazard because increases in ambient air temperature reduce both lift and engine power. This is a particular issue for operations in close proximity to power generation equipment. These aerodynamic effects can be studied at the design concept stage, and the results used by aircraft operators and pilots to maximise the safe and efficient operation of the airport or heliport.

Long span bridge aerodynamics
Wind effects are important in the design and construction of long span bridges due to their slender and flexible form. For very long spans, aerodynamic stability of the deck at high wind speeds often governs the design due to the potentially catastrophic nature of instabilities such as flutter. At lower, more frequently occurring wind speeds, vortex shedding can cause structural fatigue and degrade user comfort. The construction phase can also be critical due to less favourable structural and aerodynamic properties at key stages of erection. BMT Fluid Mechanics has a range of specialist capabilities for physical and numerical modelling that provide a comprehensive consultancy service for the design of modern long span bridges. View »

Aerodynamics of large roof structures
Wind effects are often the driving factor in the design of large roof structures. In particular, turbulent wind flows have the potential to exert significant loading on large lightweight roof structures including augmentations due to dynamic effects. Wind flows are important for the environmental and serviceability design of the enclosed, as well as the external spaces. BMT Fluid Mechanics provides a comprehensive range of consultancy services to assist design teams during planning, preliminary and final design stages.. View »

Aerodynamics of large sport stadia
Wind effects are an extremely important aspect in the design of tall buildings. Wind loading can often be the dominant load case, with significant increases in loading due to the dynamic effects. Dynamic response can also lead to high accelerations which affect occupant comfort. In addition, tall buildings tend to deflect high-level winds down to the ground level, affecting the local wind environment at the base of the building. View »
