Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

      Abstract

      Erosion is a large problem in many industries. CFD modelling is used to model the process in order to enable the engineer to design better equipment. This paper discusses a novel solution to reduce computational effort, using OpenFOAM to combine two exiting solvers. The two phases of the bulk flow are modelled partially in the Eulerian-Eulerian reference frame, and partially in the Eulerian-Lagrangian frame. The method aims to reduce computational time, but still keep the necessary particle impact data at the wall required for erosion modelling. This paper is a continuation of a previous paper which was concentrated on the development of the new hybrid solver. The new solver was applied to different geometries and test cases, and was validated against experimental data. A submerged jet impingement test with different shaped impingement samples was used to generate experimental data of the fluid phase. The results show a promising outlook for the new solver to be used for more efficient erosion prediction.
