WebInline means that the cylinder is oscillating parallel to the incoming flow. This kind of configuration is often used to validate solvers aiming to simulate large body motions (see e.g. [1, 4, 5]). The reason is that that despite its simplicity this configuration is associated with a variety of complex physical phenomena. Web1 de mar. de 2009 · Abstract. The present paper focuses on the analysis of two- and three-dimensional flow past a circular cylinder in different laminar flow regimes. In this simulation, an implicit pressure-based finite volume method is used for time-accurate computation of incompressible flow using second order accurate convective flux …
WebIn order to simulate this kind of flow configurations, OpenFOAM offers two different approaches: the overset methodology and the morphing mesh method. The latter can be … Web26 de mar. de 2024 · In this chapter, we apply the energy gradient theory (Dou 2004, 2006) to analyze the Taylor-Couette flow between concentric rotating cylinders, and aim to …
Web1 de ago. de 2024 · Over the range of conditions encompassed in this study, the rotation of the cylinder tends to stabilize the flow for a Newtonian fluid, whereas for a viscoelastic FENE-P fluid, it first induces an inertio-elastic instability which thereby destabilizing the flow with further increase in the rotation rate, viscoelasticity tends to stabilize the flow.
