Study of mesh deformation features of an open source CFD package and application to a gear pump simulation

Abstract

A study of the mesh deformation capabilities of an open source Computational Fluid Dynamics (CFD) package is presented in this document. First, previous works on the matter are explained, and an introduction to dynamic meshes and a description of OpenFOAM, the chosen CFD package, are presented. Second, the steps needed to perform the two-dimensional simulation of an oil gear pump are developed in detail. Those steps include meshing the geometry, moving the mesh and finally solving the flow. The final part of this study includes the results and some conclusions, and possible future and derived works are listed. At the end of the document the budget of the study, environmental concerns and the bibliography and references are presented.
