Wind Tunnel Testing Benefits
Testing using a wind tunnel is an essential part of designing in numerous industries, typically used for verification, and tuning of aerodynamic properties of objects. An object may be in motion or stationary, wind tunnel testing offers insights into how air and wind affect the test model as it moves around it or over it. In fields such as the construction and/or engineering of tall buildings, roofs, bridges, aerospace parts, vehicles, stadiums, and building facades use wind studies.
What Are The Benefits of Wind Tunnel Testing?
When engineers and architects pour their energies into designing structures using state-of-the-art materials combined with unique designs and shapes, they need to be able to ensure that their designs will hold up in the real world.
A good example is enhancing natural ventilation within structures. Natural ventilation does not consume energy, whereas, for a building equipped with mechanical ventilation, the energy consumption is considerable.
Using natural ventilation as much as possible will positively benefit a structure as it will help mitigate costs related to power consumption. Wind tunnel tests, combined with CFD wind analysis are reliable tools for determining the effect that natural ventilation has on structures. They allow designers to optimise the shape, location, and size of ventilation inlets and outlets.
A common occurrence that results from natural ventilation that needs serious consideration by building designers is the chimney effect or the stack effect. “Stack effect” is when the temperature on the exterior of a tall building is colder than the temperature inside it. As warm air tends to rise, indoor air presses upward to leave the building via openings in the higher floors. A stack effect analysis will help control the stack ventilation, which will greatly improve passive cooling during hot weather while allowing for minimal maintenance and better cost-efficiency because of lower energy and construction costs for new structures.
