Large Eddy Simulation of Circular Cylinder Flow by Using Higher Order WENO Schemes
نویسندگان
چکیده
This paper investigates the feasibility of a high order finite difference weighted essentially nonoscillatory(WENO) scheme for large eddy simulations(LES) with implicit subgrid scale model. In this paper, the 5th-order WENO scheme with a conservative 4th-order central differencing for viscous terms are used to simulate the flow past a circular cylinder at ReD = 3900. The turbulent effects near wake with different spanwise length (1D and πD) are studied. The comparison of the simulations with implicit subgrid scale model and with Smagorisky SGS model is also presented.

Comparison of High Order Schemes for Large Eddy Simulation of Circular Cylinder Flow
This paper compares LES results of a cylinder flow with two sets of numerical schemes, two span lengths, and a coarse and refined mesh. One set of the numerical scheme is the 7th order WENO scheme for the inviscid fluxes and 6th order central differencing for the viscous terms (7-6), the other set is a 5th order WENO scheme with a 4th order central differencing(5-4). For this purpose, a fully c...
متن کاملAccelerating high-order WENO schemes using two heterogeneous GPUs
A double-GPU code is developed to accelerate WENO schemes. The test problem is a compressible viscous flow. The convective terms are discretized using third- to ninth-order WENO schemes and the viscous terms are discretized by the standard fourth-order central scheme. The code written in CUDA programming language is developed by modifying a single-GPU code. The OpenMP library is used for parall...
متن کاملA Numerical Study on the Aeroacoustic Radiation from a Finite Length Rotating Cylinder
Rotating cylinders have wide applications in different areas, especially the aerodynamic area. However, the acoustic behaviors of these components have not been widely studied. The generating noise from a spinning cylinder is mainly due to the detached vortices from the leeward of the body. In this study, the large eddy simulation technique is used to simulate the flow field over a three-dimens...
متن کاملDiscrete-velocity relaxation methods for large eddy simulation
A new discrete-velocity method for the numerical solution of large eddy simulation (LES) is presented based on relaxation type formulation. The discrete-velocity equations are derived from the continuous Boltzmann equation with appropriate scaling suitable for incompressible flows. The turbulence effects are incorporated in the system by considering the Smagorinsky model. A higher-order relaxat...
متن کاملAIAA 2003–4085 Evaluation of a Second-Order Accurate Navier-Stokes Code for Detached Eddy Simulation Past a Circular Cylinder
We evaluate the applicability of a production computational fluid dynamics code for conducting detached eddy simulation for unsteady flows. A second-order accurate Navier-Stokes code developed at NASA Langley Research Center, known as TLNS3D, is used for these simulations. We focus our attention on high Reynolds number flow (Re = 5× 10 − 1.4× 10) past a circular cylinder to simulate flows with ...
