Incompressible Flow Computations (Part I of III)

The current direction in numerical methods for incompressible fluid dynamics emphasizes the efficient formulation of high resolution methods to compute unsteady turbulent flows and to choose numerically correct boundary conditions, using the techniques such as adaptive mesh refinement, domain decomposition and preconditioners.

The speakers will present the latest developments in this important field. They will discuss new development of highly efficient methods including projection methods, spectral methods and vortex methods. They will also discuss how to handle complex geometries, how to accelerate convergence by multigrid and how to increase resolution by local mesh refinement.
