Abstract
A novel approach towards the input-output oriented modelling of hydraulic transmission lines is applied to the so-called wave converter in this paper.
If the Reynolds number is low enough to justify the assumption of laminar flow and if convective terms are negligible, the governing equations are linear and a very compact description of the input-output behaviour of the transmission line dynamics in the frequency domain.
For a coupled simulation of networks of transmission lines interacting with other, possibly nonlinear components such as valves, there are numerous approaches for the approximation of the transcendental transfer functions arising from the transmission line dynamics by finite dimensional models in the time domain.
The proposed method for the derivation of a reduced order model offers a trade-off between the degree of accuracy and the system order.
Important properties like the passivity of the transmission line model and the exact fulfillment of the Joukowsky relation are guaranteed.
