Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Historically, piping networks in the wet end of paper machines are assumed to add little to the dynamics outside pure transport delay. Consequently large vessels are included simply to dampen incoming stock concentration variations. This paper challenges this assumption by showing that including mixing and inertia terms in the piping equations, the pipe layout has a large effect in the important region of 10[-3] to 10[-1] Hz where stock concentration variations are present, but are outside the influence of the regulatory control systems.
