Summary on Grant Application Form |
|
The aim of the work is to develop and implement a new method of numerical simulation of wave diffraction phenomena, with particular reference to high frequency problems in which the wavelength under consideration is short in comparison with the problem dimension. The new approach will be based on the Boundary Element Method (BEM), and will focus on the inclusion of a sinusoidal term in the element shape function. This causes the primary variable to become not the pressure itself, but the envelope of the pressure. Since the variation of the wave envelope is considerably less rapid than that of the pressure, this development will allow the lifting of the well-known restriction of numerical simulation methods which requires that at least ten nodes be used per full wavelength. This will extend the scope of BEM techniques to higher frequency problems which have hitherto been difficult to analyse accurately.
