Tools and Technologies

The ANTC incorporates diverse expertise in both experimental techniques and computational technologies. The Centre is able to utilise the facilities at the University which include a selection of wind tunnels and computing clusters. 

Wind tunnels and technologies

Experimental facilities at the University include a range of low speed wind tunnels for aerodynamic and acoustic measurements. There is also a large anechoic chamber at ISVR. The anechoic chamber has internal dimensions of 9.15 m x 9.15 m x 7.32 m. The wedge length is 0.91 m giving free-field conditions at frequencies above 80 Hz. The University of Southampton is currently building a new anechoic wind tunnel at the Boldrewood campus. This will be part of the National Wind Tunnel Facilities. It is a closed return, open jet wind tunnel. The nozzle dimensions are 1 m x 0.75 m and the maximum flow velocity is 80 m/s. The internal dimensions of the anechoic chamber are 8.1 m x 4.4 m x 5.5 m. It is due for completion in 2018.

Computational Facilities

The University's high performance state-of-the-art computing clusters are utilised to run an in-house code, known as SotonCAA, for large-scale parallel computing.

Computational facilities include:



The high-order computational aeroacoustics program SotonCAA has been developed within the centre and is at the forefront of numerical noise prediction technology.
