RANS Predictions of Turbulent Flow Past a Circular Cylinder over the Critical Regime
Incompressible, turbulent flow past a circular cylinder is computationally investigated by means of Reynolds Averaged Numerical Simulations. Problems in using the wall-functions approach for modeling the near-wall turbulence are demonstrated. As the main turbulence model, the Shear Stress Transport model is employed, by resolving the nearwall layer. A wide range of Reynolds numbers is investiga...
متن کاملEffect of the Spanwise Discretisation on Turbulent Flow past a Circular Cylinder
The effect of the spanwise discretisation on numerical calculations of the turbulent flow around a circular cylinder is systematically assessed at a subcritical Reynolds number of 10000 in the frame of three-dimensional large-eddy simulation. The eddy-viscosity k-equation subgrid scale model is implemented to evaluate unsteady turbulent flow field. Large-eddy simulation is known to be a reliabl...
متن کاملNumerical 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 ...
متن کاملMixed Convection Flow in a Rectangular Ventilated Cavity with a Heat Conducting Solid Circular Cylinder at the Center
A numerical investigation has been carried out for mixed convection flow in a rectangularventilated cavity with a heat conducting solid circular cylinder at the center. Forced convection flowconditions were imposed by providing an inlet at the bottom of the left wall and an outlet vent at the topto the other sidewall. In this paper, the effect of cavity aspect ratio as well as the mixed convect...
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...
