Computation tool for predicting noise from water jet tunnel

An analytical computation model of water jet tunnel uses the solution of the coupled problem water – tunnel walls to predict the vibration and the resulting sound radiation from the tunnel. The tunnel is modelled as an elastic cylindrical shell. The result can be applied to noise modelling in frequency bands.

The model is currently tested in laboratory, by comparing computation with measurements on a scaled-down water filled shell. Good overall matching was found.
