Summary on Grant Application Form |

The work proposed here seeks to develop new computational methods for simulating wave propagation on mean flows in situations where the wavelength of the disturbance is small compared to the dimensions of the solution domain. Such problems are common in flow acoustics and are of particular interest in the context of sound propagation in turbofan inlets, an area of pressing importance in reducing aircraft noise. The current proposal seeks to establish whether numerical schemes based on the 'partition of unity' approach will be effective for such problems. The partition of unity method is a modified Finite Element (FE) scheme in which a conventional FE trial solution is enriched by the use of local approximations based on propagating plane wave solutions. The proposed work is very much a feasibility study. It does not seek to apply PUM schemes to industrial scale problems but merely to demonstrate their utility using simple model problems in one and two dimensions. The current proposal is submitted as a faststream project in the expectation that it will be followed by a more extensive proposal if feasibility is estalished.
