Slurry Transport: Fundamentals, A Historical Overview & The DHLLDV Framework.

   03 Uniform Sands & Gravels
The DHLLDV Framework is based on the spatial volumetric concentration in the pipe and uniform sands or gravels and consists of a framework containing 12 sub-models.
  1. The fixed or stationary bed model.
  2. The sliding bed model.
  3. The heterogeneous transport model.
  4. The homogeneous transport model.
  5. The sliding flow transport model.
  6. The limit deposit velocity model.
  7. The holdup or slip factor model.
  8. The concentration distribution.
  9. The transition heterogeneous-homogeneous flow.
  10. The bed height model.
  11. Graded sands & gravels.
  12. Inclined pipes.
