Stratified flow phenomena are prevalent throughout the oceans. We present the results of laboratory experiments that study several ocean inspired problems, including: the settling of marine snow, spontaneous propulsion of asymmetric objects and the generation of internal wave beams by topography. These experiments cover a large range of physical scales, from as small as 100 microns for the settling of marine snow to several meters for internal wave generation, emphasizing the richness of interesting and important research problems is stratified flow
Dr. Tom Peacock of Dept. of Mechanical Engineering, MIT is a visitor at the BILAT-program. He is an expert on theoretical physics, and does currently theoretical, experimental and field work on internal waves in the ocean.

In a recent Ph.D. project the possibility of applying the Discontinuous Galerkin spectral/hp element method for the next generation of Boussinesq-type models has been investigated. These numerical methods have reached a level of maturity that turns them into an attractive alternative to the existing Boussinesq-type models, which traditionally have been based on finite difference methods in structured domains. In particular, we seek to take advantage of the geometrical flexibility of spectral/hp finite element methods to enable us to solve wave problems in increasingly complex environments. A nodal discontinuous Galerkin finite element method (DG-FEM) is used for the spatial discretization to solve a recently derived set of high-order Boussinesq-type equations [1] in complex and curvilinear geometries, and thereby amends the application range of previous numerical models. The new Boussinesq method allows for the accurate description of fully nonlinear and dispersive water waves in both shallow and deep waters, and to demonstrate and investigate the applicability of the model both linear and nonlinear test cases have been considered where water waves interact with bottom-mounted fully reflecting structures.
