4. 2. Seismic investigations and physical property studies of natural resources in Finland and Sweden : Efficient exploration of groundwater and mineral resources

   Author : Georgiana Maries; Alireza Malehmir; Christopher Juhlin; Musa Manzi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; seismic refraction; esker; glacial sediments; iron-oxide; hardrock; efficient exploration; physical property; forward modeling; seismic quality factor; Finland; Sweden; Bergslagen;

   Abstract : Natural resources, such as mineral deposits and groundwater in particular, are crucial for our society, as the world prepares itself for a smooth transition towards green technologies and decarbonization. Apart from extraction and use, innovative mineral exploration solutions are needed to complete the full value chain and to achieve the sustainable development goals. READ MORE

   Abstract : Surface gravity waves in the world’s oceans contain a renewable source of free power on the order of terawatts that has to this date not been commercially utilized. The division of Electricity at Uppsala University is developing a technology to harvest this energy. READ MORE

6. 4. The Full Multigrid Method Applied to Turbulent Flow in Ventilated Enclosures Using Structured and Unstructured Grids

   Author : Peter Emvin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adaptivity; finite volume; local mesh refinement; finite element; k-omega large Eddy simulation; ventilated enclosure; k-epsilon; multigrid;

   Abstract : Computational fluid dynamics require large computer resources and it is thus of paramount interest to have as efficient an algorithm as possible. This means that both an accurate discretization and a fast solver are required. In this work, we have used the full multigrid concept, which is a general and optimal solver. READ MORE

7. 5. Adaptive Finite Element Methods for Compressible Two-Phase Flow

   Author : Erik Burman; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive finite element methods; two-phase flow; compressible flow; conservation laws; hyperbolic systems; a posteriori error estimates; streamline diffusion; stability analysis; quantitative error control; adaptive algorithms; quantitative error control;

   Abstract : In this thesis we develop, apply and analyse adaptive finite element methods with error control for compressible flow problems, focusing in particular on two-phase flow. The adaptive algorithms, aiming at quantitative error control with efficient use of computational resources, are based on a posteriori error estimates, where the error is estimated in terms of the computed solution, the local mesh-size and certain stability factors.
