An efficient cellular flow model for cohesive particle flocculation in turbulence
K. Zhao, B. Vowinckel, T. -J. Hsu +3
We propose a one-way coupled model that tracks individual primary particles in a conceptually simple cellular flow setup to predict flocculation in turbulence. This computationally…
Confronting Grand Challenges in Environmental Fluid Mechanics
T. Dauxois, T. Peacock, P. Bauer +10
Environmental fluid mechanics underlies a wealth of natural, industrial and, by extension, societal challenges. In the coming decades, as we strive towards a more sustainable plane…
Consolidation of freshly deposited cohesive and non-cohesive sediment: particle-resolved simulations
Bernhard Vowinckel, Edward Biegert, Paolo Luzzatto-Fegiz +1
We analyze the consolidation of freshly deposited cohesive and non-cohesive sediment by means of particle-resolved direct Navier-Stokes simulations based on the Immersed Boundary M…
Momentum balance of a laminar flow over a bed of particles
E. Biegert, B. Vowinckel, E. Meiburg
We develop a framework for analyzing the momentum balance of laminar particle-laden flows based on immersed boundary methods, which solve the Navier-Stokes equations and resolve th…
Settling of cohesive sediment: particle-resolved simulations
B. Vowinckel, J. Withers, P. Luzzatto-Fegiz +1
We develop a physical and computational model for performing fully coupled, particle-resolved Direct Numerical Simulations of cohesive sediment, based on the Immersed Boundary Meth…
