    hydrofoils. N
JS and cloud height at high solids concentrations. Future work proposals.

12:30 – 13:30      Lunch

13:30 – 14:15      External Presentations:

   Vortexes in Unbaffled Tanks a literature review and some lost data. by A.W.Etchells and

    Further exploration of the yield stress tunnelling phenomenon. Latest results on
    mixing length and pressure drop measurements and correlation with non-Newtonian
    bulk flows (shear-thinning, yield stress and viscoelastic). Future work proposals.
