Flexible hose models

This page under construction

This page contains a model for flexible hose incorporating dynamic wave propagation behaviour, including coupled wall and fluid waves, and viscoelastic damping. This model was published in:

Johnston, D. N., A Time Domain Model of Axial Wave Propagation in Liquid-Filled Flexible Hoses, Proc IMechE, part I, Vol 220, No. 7, pp517-530

These models may be downloaded for research use. We accept no liability for any problems arising from their use.

All models were created using Matlab R2009b. The models should run without any changes needed; they are set up with typical parameters and some simple boundary conditions.
