MATHEMATICAL ANALYSIS OF CHANNELISATION IN NONNEWTONIAN LAMINAR DEPOSITION FLOW
Arno Talmon
Source abstract
Channel formation is a common feature in the deposition of tailings. It is unknown how this initiates. It is investigated if channel formation in laminar flow can originate from hydrodynamics only. An analytical linearised approach is followed in order to establish a theoretical basis and a reference for further developments. It shows that thixotropy can govern pattern formation. Observations in tailings deposition flume testing are applied for reference. It is concluded that sidewall friction influences system behaviour in a similar way, and is here held responsible for meandering.
