Direct numerical simulation of particle sedimentation in a Bingham fluid
A. R. Koblitz, S. Lovett, N. Nikiforakis
The settling efficiency, and stability with respect to settling, of a dilute suspension of infinite circular cylinders in a quiescent viscoplastic fluid is examined by means of dir…

On the viscoplastic squeeze flow between two identical infinite circular cylinders
Arndt Ryo Koblitz, Sean Lovett, Nikolaos Nikiforakis
Direct numerical simulations of closely interacting infinite circular cylinders in a Bingham fluid are presented, and results compared to asymptotic solutions based on lubrication…

Direct numerical simulation of particulate flows with an overset grid method
A. R. Koblitz, S. Lovett, N. Nikiforakis +1
We evaluate an efficient overset grid method for two-dimensional and three-dimensional particulate flows for small numbers of particles at finite Reynolds number. The rigid particl…
