We present a large-level request for storage allocation on high-performance computing (HPC) resources within the Swedish National Infrastructure for Computing (SNIC). In particular, we request for 1,200,000 GiB storage on Klemming PDC (120 million files), 400,000 GiB on Centre Storage NSC, 120,000 GiB on Nobackup HPC2N (18 million files) and 200 TiB on iRODS. The ongoing research is conducted by the research group Micro Complex Flow, at the Linne FLOW Centre, (VR Excellence Centre) at KTH Mechanics. The group, with Prof. Brandt as PI and Profs. Lundell, Bagheri and Mihaescu, Assoc. Profs. Dahlkild , Duwig, Prahl Wittberg and Tammisola as Co-Invertigators, consists of a total of 40 senior researchers, Postdocs and PhD students, with at least 3 to be hired during the year.
There are currently 26 ongoing research projects (see proposal for computational time) that rely entirely on compute and storage allocations provided by SNIC. These projects are grouped in five focal areas as below:
1. Complex fluids: Simulations of non-Newtonian fluids and flows with a microstructure (particles, bubbles, droplets in laminar and turbulent regimes).
2. Flow at interfaces: Simulations of flows over porous, elastic, poro-elastic and micro-structured interfaces.
3. Bio-physical flows: Simulations of the flows within the cardiovascular and respiratory systems, and cell transport.
4. Multiphase and free-surface flows with phase change: multiphase flows that account for complex physical phenomena such as phase change, absorption/desorption, buoyancy-induced convection to study bubble/droplet spreading, breakup during evaporation and boiling process.
5. Unsteady flows for clean vehicles: Simulations of compressible flows, with heat- and mass-transfer associated with energy conversion and propulsion systems, to reduce pollutants and noise and improve efficiency.
