Transient Semi Circular Lid Driven Cavity Flow Using Non Uniform Structured Grid Method with Upwind Scheme

摘要: In this article, two-dimensional lid-driven cavity flow in a semi-circular is simulated using non-uniform finite different method with structured grid. NavierStokes and continuity equations are simplified non-dimensional streamfunction– vorticity approach. A Reynolds number of 1000 used and the and streamfunction contour plot monitored convergence criteria 1x10-7 set to both streamfunction value. The result shows that primary vortex moves from upper left corner right corner, while magnitude grows at center. size decreases steadily as time increases. This phenomenon greatly affected by increasing size secondary lower left. Slight changes size are observed achieves steady state condition. Validation simulation results current value deviation established less than 5%. future, it recommended use better numerical so more stable calculation can be reduced.
