Uncertain data assimilation for urban wind flow simulations with OpenLB-UQ
arXiv.orgAccurate prediction of urban wind flow is essential for urban planning, pedestrian safety, and environmental management. Yet, it remains challenging due to uncertain boundary conditions and the high cost of conventional CFD simulations. This paper presents the use of the modular and efficient uncertainty quantification (UQ) framework OpenLB-UQ for ...

Binary mixture flow with free energy lattice Boltzmann methods [PDF]
arXiv.org, 2022 We use free energy lattice Boltzmann methods (FRE LBM) to simulate shear and extensional flow of a binary mixture in two and three dimensions. To this end, two classical configurations are digitally twinned, namely a parallel-band device for binary shear

Energy Technology, Volume 10, Issue 12, December 2022., 2022 A numerical framework is presented highlighting effects of compressive stress on fluid transport across multiple porous layers in polymer electrolyte membrane fuel cells. Liquid transport characteristics under various compressive conditions are mainly influenced by pore‐scale capillary pressure.
