Particle-resolved simulations of settling particles: A methodology for long time-integration intervals
M. Moriche, M. García-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 García-Villalba, Jan Dušek +2
The present work extends the direct-forcing immersed boundary method introduced by García-Villalba et al. (2023), broadening its application from spherical to arbitrarily-shaped pa…
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…
An efficient method for particle-resolved simulations of neutrally buoyant spheres
Manuel Garcia-Villalba, Blanca Fuentes, Jan Dusek +2
We present a simple modification of the direct-forcing immersed boundary method (IBM) proposed by Uhlmann [J. Comput. Phys, 2005] in order to enable it to be applied to particulate…
On the clustering of low-aspect-ratio oblate spheroids settling in ambient fluid
Manuel Moriche, Daniel Hettmann, Manuel García-Villalba +1
We have performed particle-resolved direct numerical simulations of many heavy non-spherical particles settling under gravity in the dilute regime. The particles are oblate spheroi…
A single oblate spheroid settling in unbounded ambient fluid: a benchmark for simulations in steady and unsteady wake regimes
Manuel Moriche, Markus Uhlmann, Jan Dušek
We have performed spectral/spectral-element simulations of a single oblate spheroid with small geometrical aspect ratio settling in an unbounded ambient fluid, for a range of Galil…
On the aerodynamic forces on heaving and pitching airfoils at low Reynolds number
Manuel Moriche, Oscar Flores, Manuel Garcia-Villalba
The influence that the kinematics of pitching and heaving 2D airfoils have on the aerodynamic forces is investigated using Direct Numerical Simulations and a force decomposition al…
