A fundamental study of the flow past a circular cylinder using Abaqus/CFD
Abstract: The latest release of Abaqus version 6.10 includes Abaqus/CFD. The inclusion of this software makes it possible for users to perform a fluid analysis in a more user-friendly manner. Independent single software solely for CFD is currently available from many developers, and many attempts have been made to link software of CFD to structural analysis system using some specific procedures...
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 کاملNumerical Simulation of Fluid Flow Past a Square Cylinder Using a Lattice Boltzmann Method
The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions. In the presen...
متن کاملRANS 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...
