Numerical Simulation of Nonlinearly Viscous Fluid Flows in a Two-Dimensional Cavity
ABSTRAKT
The article addresses a problem of determination of a steady flow of nonlinearly viscous incompressible fluid in a two-dimensional cavity with a velocity prescribed over its boundary. The method of augmented Lagrangian and approximation by the finite elements are used to obtain the numerical solution. Numerical simulation of viscous and nonlinearly viscous fluid flows in a square cavity with driving top wall is performed. Results of calculations on the fine mesh allow to describe the eddy structures. Comparison with results in newtonic fluids is given.
