In recent years, projects combining wind tunnel testing facilities with anechoic chambers have been increasing.
What is a Wind Tunnel (Wind Tunnel Laboratory)?
It is a device or facility that artificially generates small-scale flows to replicate and observe actual flow fields. Test models such as scaled-down models are placed within the generated flow to measure local wind speeds, pressure distributions, forces, torques, and visualize flows. Experiments conducted using wind tunnels are known as wind tunnel experiments or wind tunnel tests, and they are used in the design of transport machinery such as aircraft, railway vehicles, automobiles moving at high speeds, as well as in structures prone to wind effects like tall buildings and bridges.
These facilities often span large dimensions, with wind tunnels alone reaching lengths close to 50 meters, making even preliminary assembly before factory shipment quite extensive.
In the design of a wind tunnel laboratory combined with an anechoic chamber, various components are included such as blowers, diffusers, air conditioning coils, corner vanes, settling chambers, flow straighteners, and contraction sections, alongside designing silencer ducts. Environmental conditions inside are set, including airflow temperature ranges and wind speed ranges (e.g., 20 to 260 km/h), controlled via inverters.
The anechoic chamber is designed considering conditions such as measurable lower limit frequencies, sound insulation levels, ambient noise, and noise values at measurement points.
Achieving these conditions is crucial for establishing the measurement chamber, requiring diverse knowledge and experience. Our company has a wealth of experience in integrating anechoic chambers into wind tunnel testing facilities, so you can trust us with your project.
