Towards PR-DNS of scour around a wall-mounted cylinder in turbulent open channel flow
Leo Bürk, Artjom Hermann, Markus Weyrauch +1
Particle-resolved direct numerical simulation (PR-DNS) is performed for turbulent open channel flow over a smooth horizontal wall with a vertical cylinder and a dilute set of mobil…
How far does the influence of the free surface extend in turbulent open channel flow?
Christian Bauer, Yoshiyuki Sakai, Markus Uhlmann
Turbulent open channel flow is known to feature a multi-layer structure near the free surface. In the present work we employ direct numerical simulations considering Reynolds numbe…
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…
Results from Particle-Resolved Simulations
Agathe Chouippe, Aman G. Kidanemariam, Jos Derksen +2
We review some of the results obtained to date with the aid of the PR-DNS approach to turbulent particulate flows. It is shown that the method has matured to a point which allows t…
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…
