Large Eddy Simulation (LES) of a Steady Turbulent Flow over a Surface-Mounted Cube

摘要

? The aim of this work is to simulate a steady turbulent flow over a surface-mounted cubicle obstacle using techniques in computational fluid dynamics (CFD). The simulation was done using an in-house code developed in the programming platform of Visual C++. The Finite Volume Method was used to compute numerically the solutions of the Navier-Stokes equation under turbulent conditions. The Quadratic Upstream Interpolation for Convective Kinetics (QUICK) numerical scheme was utilized with the Semi-Implicit Pressure Linked Equations (SIMPLE) as an algorithm. The code consists of a steady three-dimensional turbulent solver using the Large Eddy Simulation (LES) turbulent model . ?The simulated velocity flow profile is then compared against experimental data. ?
