Simulation of turbulent flows by large vortex methods in the OpenFOAM package

Reporter: Kalmurzaeva A.T.


This paper presents the numerical results of the problems of modeling three-dimensional incompressible fluid flows. The simulation is based on three-dimensional non-stationary, space-averaged Navier-Stokes equations. The numerical solution of the Navier-Stokes equations system was carried out using the stationary solver pisoFoam package OpenFOAM 6. The adequacy of the mathematical model is checked by comparison with the corresponding experimental data.
Keywords: Unsteady flow, turbulence, large vortex method, pisoFoam, OpenFOAM.

Some test problems of modeling turbulent flows are considered [1]. Numerical solutions of the nonstationary Navier-Stokes equations using a nanostructured computational grid [2] are based on the finite volume method [3]. For numerical simulation, the pisoFoam solver of the OpenFOAM open software package [4] was used.
In fig. Figure 1 shows the geometry of the test problem of a separated flow in a three-dimensional channel with a sudden expansion and confused compression at the outlet, and in fig. 2 shows the speed field.
