WebThe purpose of the present paper is, to give an overview of the different techniques available in openFOAM for simulation of rotating flow problems. It is stated that unsteady flow … 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.

The intensity of magnetic field is fixed at Ha = 0 and 100, which has the substantial outcome on the heat transfer and fluid flow structures. 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.
