Line Stretching in Random Flows
Daniel Lester, Marco Dentz
How finite-sized material lines stretch in chaotic (mono-scale) and turbulent (multi-scale) flows remains a central but unresolved problem that governs mixing, transport and reacti…

Sedimentation of particulate suspensions under stagnant conditions in horizontal pipes
Tanmoy Das, Daniel Lester, Anthony Stickland +1
Sedimentation of particulate suspensions in horizontal pipes can lead to formation, growth and consolidation of a solid-like bed which can severely retard pipeline performance. As…

Turbulent Pipe Flow of Thixotropic Fluids
Noman Yousuf, Daniel Lester, Murray Rudman +2
Complex materials with internal microstructure such as suspensions and emulsions exhibit time-dependent rheology characterized by viscoelasticity and thixotropy. In many large-scal…
