Capillary damping of inviscid surface waves in a circular cylinder
We consider the effect of a wetting condition at the moving contact line on the frequency and damping of surface waves on an inviscid liquid in a circular cylinder. The velocity potential φ and the free surface elevation η are sought as complex eigenfunction expansions. The φ eigenvalues are the classical ones whereas the η eigenvalues are unknown and have to be computed so as to satisfy the we...
متن کاملSurface-wave damping in a brimful circular cylinder
The natural frequencies and damping rates of surface waves in a circular cylinder with pinned-end boundary conditions are calculated in terms of the gravitational Reynolds and Bond numbers, C and B, and the slenderness of the cylinder A, in the limit C —>• 0. We consider higher-order approximations that include the effect of viscous dissipation in the Stokes boundary layers and the bulk. A comp...
متن کاملCharacteristics of vortices shed from a circular cylinder and an inclined flat plate
Vortex shedding from a circular cylinder and from an inclined flat plate is computed with a finite volume CFD code with RNG k-ε turbulence model. The wake behind the circular cylinder consists of two trains of vortices of equal strengths. Dependence of vortex patterns on Reynolds numbers at Re between 10 and 10 is investigated. Flow over the inclined flat plate is asymmetric and unequal charact...
متن کاملSuppression of vortex-induced forces on a two-dimensional circular cylinder by a short and thin splitter plate interference
This paper briefly reviews bluff body aerodynamics and focuses mainly on the use of short and thin splitter plates to interfere with the vortex wakes and suppress vortex-induced forces (VIF). The present investigation primarily examines the suppression of unsteady, two-dimensional wake instabilities over a low Reynolds number range of less than 250. A circular cylinder is used as the bluff body...
متن کاملThermal Field Around a Circular Cylinder with Periodic Vortex Shedding
A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...
