A high-frequency BEM for 3D acoustic scattering
Presentation / Conference
Hargreaves, J., Lam, Y., Langdon, S., & Hewitt, D. A high-frequency BEM for 3D acoustic scattering. Presented at 22nd International Congress on Sound and Vibration, Florence. Italy

The Boundary Element Method (BEM) is a powerful method for simulating scattering of acoustic waves which has many advantages, particularly when the problem concerns an object in an unbounded medium. Its applications are however limited in practice be... Read More about A high-frequency BEM for 3D acoustic scattering.

Acoustic cross-energy measures and their applications
Presentation / Conference
Hargreaves, J., & Lam, Y. Acoustic cross-energy measures and their applications. Presented at The 22nd International Congress on Sound and Vibration, Florence. Italy

Acoustic energy density and acoustic intensity are quantities which are well established and widely applied. When these are applied to pressure and particle-velocity fields which are the linear superposition of more than one wave they naturally separ...
