| 中文摘要 | Both the large eddy simulation (LES) technique and the k-epsilon turbulent model were used to simulate the gas-liquid turbulent flow in a stirred tank driven by a Rushton impeller. A Eulerian-Eulerian two-fluid model for gas-liquid two-phase flow, was developed using the large eddy,v simulation for both gas (aid liquid phases. The relative baffles was accounted for through the movement of the rotating impeller to the static baffles 'improved inner-outer iterative algorithm. The spatial discretization of the governing equations was performed on a cylindrical staggered grid. For the LES, a conventional Sniagorinsky,v sub-grid model was adapted to modeling the turbulence of the liquid phase. The momentum and continuity equations were discretized using the finite diffrence method, ",ij'h a third order QUICK (Quadratic Upwind Interpolation tor Convective Kinematics) scheme used for convective terms. The phase-resolved predictions of the LES were compared with the experimental data and the simulation results by the standard k-epsilon model, suggesting that the LES has much better accuracy than the k-epsilon model.
