Developing the state-of-the-art...
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 wind tunnels for aerodynamic and acoustic measurements including a large 11' by 5' closed jet wind tunnel and an open jet anechoic chamber. The Centre adopts advanced techniques such as Particle Image Velocimetry (PIV) for aerodynamic measurements, and phased microphone array for acoustic source mapping.
Computational Methods:
The high-order computational aeroacoustics program SotonCAA has been developed in the Centre and is at the forefront of numerical noise prediction technology.
Details of the SotonCAA program:
- Large-eddy and detached-eddy simulations
- Reynolds averaged Navier-Stokes equations
- Linearised Euler and acoustic perturbation equations
- Spatial derivatives: 6th order pre-factored and optimised compact schemes
- Time integration: 4th-order 4/6 stage RK and 2nd order implicit schemes
- Boundary conditions: slip wall, buffer zone, time domain impedance, characteristic, etc.
- Curvilinear coordinates, multi-block, structured grids
- Parallel solutions running MPI on window and Linux PC clusters
- Integral solution of Ffowcs Williams and Hawkings equation
Computational facilities:
The University's high performance state-of-the-art computing clusters are utilised to run the SotonCAA code for large-scale parallel computing.
Computational facilities include:
- MSHPC - Microsoft High Performance Computing cluster
- Iridis Compute Cluster - Linux computing cluster based on AMD Opteron Processors
