NUMERICAL SIMULATION OF TURBULENT FLOWS IN TWO-SIDED LID-DRIVEN SQUARE CAVITY BY FINITE ELEMENT METHOD (Pages : 120 - 124)

The paper focuses on simulation of turbulent flow in a two-sided lid-driven square cavity containing an incompressible fluid using a finite element method (FEM). The flow is driven by the parallel motion to two facing walls. The top and bottom horizontal walls of the cavity are moving parallel to each one on its own plane at a constant while the left and right vertical walls are at rest. The governing equations are solved using finite element approach with a clear and simple statement using ANSYS 11.0 finite element software. A fine uniform grid mesh of 100X100 was used to simulate the flows. The numerical simulation is performed for a range of Reynolds number of 3500 to 6500 with an aspect ratio 1. Using ANSYS 11.0 finite element software, it is found that there appears a pair of counter-rotating secondary vortices of equal size near the centre of a wall. The ANSYS finite element program is useful in this study as well as varieties of enclosed fluid flows.Download
