• At <strong>the</strong> higher wall shear stress values for mixture 2 <strong>the</strong> viscous sub-layer thickness
is less than <strong>the</strong> diameter <strong>of</strong> <strong>the</strong> larger <strong>particle</strong>s.
• An increase in <strong>the</strong> representative <strong>particle</strong> <strong>size</strong> caused an increase in <strong>the</strong> wall shear
stress in <strong>the</strong> turbulent flow region.
• The Slatter model best predicted <strong>the</strong> test data and becomes more accurate with
increasing <strong>particle</strong> <strong>size</strong>.
• The Maude & Whitmore correlation is unable to accurately predict turbulent flow
behaviour.
• The Bowen correlation produces good results but does not provide an explanation <strong>of</strong>
<strong>the</strong> behaviour <strong>of</strong> <strong>the</strong> slurry in terms <strong>of</strong> <strong>the</strong> physical properties <strong>of</strong> <strong>the</strong> slurry.
• Slarter's model is unable to predict <strong>the</strong> turbulent flow behaviour <strong>of</strong> <strong>the</strong> Sive data for
a non-homogeneous settling slurry.
The results and analysis are discussed in Chapter 5.
