A simple criterion and experiments for onset of flocculation in kaolin clay suspensions
Nicholas Rommelfanger, Bernhard Vowinckel, Zixuan Wang +3
Cohesive effects between fine-grained sediment particles greatly influence their effective settling rate and erodibility. Many studies have observed a qualitative difference in set…
Flocculation of suspended cohesive particles in homogeneous isotropic turbulence
K. Zhao, F. Pomes, B. Vowinckel +3
We investigate the dynamics of cohesive particles in homogeneous isotropic turbulence, based on one-way coupled simulations that include Stokes drag, lubrication, cohesive and dire…
Rheology of mobile sediment beds sheared by viscous, pressure-driven flows
B. Vowinckel, E. Biegert, E. Meiburg +2
We present a detailed comparison of the rheological behaviour of sheared sediment beds in a pressure-driven, straight channel configuration based on data that was generated by mean…
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…
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…
