Abstract

We present a large-level request for computer time on high performance computing (HPC) resources within the Swedish National Infrastructure for Computing (SNIC). We summarize here the projects by the research group Micro Complex Flow, at the Linne FLOW Centre, (VR Excellence Centre) at KTH Mechanics. The group, with Pi's Prof. Brandt, Prof. Fuchs, Prof. Amberg, Assoc. Prof. Dahlkild, Lundell, Mihaescu, Duwig, Bagheri and Prahl Wittberg, Dr. Do-Quang and Tammisola, consists of a total of 11 senior researchers, 10 Postdocs and 19 PhD students, a total of 40 researchers and is expanding, 10 new recruitments expected in 2017. In the proposal we list 26 research projects that rely on HPC resources, grouped in five focal areas to enable a quick overview. Many researchers participate in and contribute to more than one area. 1. Suspension flows: Simulations of flows with rigid, elongated and deformable particles and droplets to study rheology, stability and turbulence. 2. Flow at interfaces: Simulations of flows over porous, elastic, poro-elastic and micro-structured interfaces 3. Bio-physical flows: Simulations of the fluid dynamics within the human cardiovascular and respiratory systems, cell transport and bacteria locomotion. 4. Multiphase and free-surface flows with phase change and capillarity:multiphase flow models that account for complex physical phenomena such as phase change, capillary forces, buoyancy-induced convection to study bubble/droplet spreading, breakup with evaporation, gasification and boiling process, etc. 5. Unsteady flows for clean vehicles: Simulations of compressible flows, with heat- and mass-transfer associated with internal combustion engines and gas turbines, to reduce pollutants, improve efficiency and reduce noise.
