We present a theoretical expression for the acoustic interaction force between small spherical particles suspended in an ideal fluid exposed to an external acoustic wave. The acoustic interaction force is the part of the acoustic radiation force on one given particle involving the scattered waves from the other particles. The particles, either compressible liquid droplets or elastic microsphere...

One of the main difficulties when modeling Underwater Wireless Sensor Network (UWSN) has to do with the environment characteristics and the acoustic signal typically used. As stated in other works, the accuracy of the acoustic propagation model and the network scenario conditions are critical to obtain reliable results. In this work we proposed a simulator framework for UWSN modeling. For that ...

This paper studies acoustic emission (AE) wave propagation in a glass fibre aluminium honeycomb sandwich panel (HSP). Of particular novelty is the quantification of through-thickness AE from one surface HSP to other, which real-world monitoring consideration for applications where instrumentation only be permissible on surface, i.e. aerofoils. Complexity was introduced specimens stages enable t...
