Investigation of Underwater Objects Separation in a Cross-Flow

Abstract

The research project has been initiated to develop a numerical algorithm and conduct a broad investigation of flow structures and their interactions with moving and ejecting objects. The numerical method is based on a spectral element approach applied to the unsteady, incompressible Navier- Stokes equations. The equations are adopted for a moving mesh system that allows the mesh to adjust dynamically to changing geometry. The method has been used to study flow patterns and forces on moving objects. Among the investigated cases are: two- and three-dimensional piston pumps, flow through an oscillating channel, an oscillating cylinder in a still fluid, an oscillating cylinder in a uniform flow, and an ejecting object from a silo.
