Particle-resolved simulations of settling particles: A methodology for long time-integration intervals
M. Moriche, M. GarcÃa-Villalba, M. Uhlmann
We present a methodology for simulating dilute suspensions of particles settling under gravity, with the main purpose of overcoming limitations of triply periodic configurations, m…
Aerodynamic performance and robustness of a nature-inspired concept for a micro-scale wind turbine
J. M. Catalán, G. Arranz, M. Moriche +3
We present direct numerical simulations of a novel concept for a micro-scale wind turbine, inspired in the mechanics of the auto-rotation of winged seeds. In this nature-inspired c…
An immersed boundary method for particle-resolved simulations of arbitrary-shaped rigid particles
Maximilian Schenk, Manuel GarcÃa-Villalba, Jan DuÅ¡ek +2
The present work extends the direct-forcing immersed boundary method introduced by GarcÃa-Villalba et al. (2023), broadening its application from spherical to arbitrarily-shaped p…
Efficient methods for particle-resolved direct numerical simulation
Markus Uhlmann, Jos Derksen, Anthony Wachs +2
In the present chapter we focus on the fundamentals of non-grid-conforming numerical approaches to simulating particulate flows, implementation issues and grid convergence vs. avai…
A Python-based flow solver for numerical simulations using an immersed boundary method on single GPUs
M. Guerrero-Hurtado, J. M. Catalán, M. Moriche +2
We present an efficient implementation for running three-dimensional numerical simulations of fluid-structure interaction problems on single GPUs, based on Nvidia CUDA through Numb…
