Numerical Simulation of Sediment-Laden Flow Around a Circular Cylinder

In this paper, the sediment-laden flow around a circular cylinder is numerically simulated in order to obtain better understanding of hydrodynamics associated. A range of cases with different Reynolds numbers (Re) are studies. The effects of the concentration of the sediment on the drag coefficient are investigated. Results show that due to the fact that the laden sand particle colliding the cy...

Numerical Simulation of Interaction of a Current with a Circular Cylinder near a Rigid Bed

The numerical modeling of a 2D flow around a horizontal cylinder near a rigid bed with the gap ratios G/D = 0, 0.2, 0.3 at Reynolds numbers 840, 4500, 9000, and 9500 is investigated by using weakly compressible smoothed particle hydrodynamics. The velocity field and the separation angles from the present simulations are compared with those obtained from the experimental measurements and are in ...

Passive Control of Flow Separation over a Circular Cylinder with Electro-Magnetic Fields: Numerical Simulation

Abstract A new second order theoretical model of the combined interaction of externally applied electric and magnetic fields and viscous incompressible fluid flows has been rewritten as a system of first order partial differential equations. The system was solved using a least-squares finite element model on an unstructured grid. The numerical algorithm is very stable and accurate. The accuracy...

Numerical Simulation of Polymer Injection in Turbulent Flow Past a Circular Cylinder

Using a code developed to compute high Reynolds number viscoelastic flows, polymer injection from the upstream stagnation point of a circular cylinder is modeled at Re 1⁄4 3900. Polymer stresses are represented using the FENE-P constitutive equations. By increasing polymer injection rates within realistic ranges, significant near wake stabilization is observed. Rather than a turbulent detached ...

Numerical simulation of the flow behind a rotary oscillating circular cylinder

A numerical study was made of flow behind a circular cylinder in a uniform flow, where the cylinder was rotationally oscillated in time. The temporal behavior of vortex formation was scrutinized over broad ranges of the two externally specified parameters, i.e., the dimensionless rotary oscillating frequency (0.110<S f<0.220) and the maximum angular amplitude of rotation ~umax515°, 30°, and 60°...
