The variables influencing the behavior of slurry flows include the orientation of the pipeline, the characteristic dimension of the conduit, flow velocity, particle size, particle size distribution, particle density, solids' concentration, and the properties of the fluid particle interface, which are determined by the compositions of the fluid and the solids. Non-Newtonian Slurries Turbulence is a natural form of fluid motion that is characterized by random eddy motions both parallel and transverse to the direction of the main flow. One of the earliest pieces of documentation, dating back to 1847, of conveying solids for industrial application was an exhaust system for dust removal from grindstones in a Peugeot plant. Pneumatic conveying is the primary means of moving solid products and intermediates between process stages and the transfer of materials to and from silos. Most of the bulk solid unloading operations rely on some kind of pneumatic transfer.
