Investigating the effect of solid powder particle size on the turbulent multi-phase flow in pipelines

Drag reduction has been first reported by Tom in 1949 due to the effect produced by polymer addition in fluids.The problem of pumping power losses in pipeline flow cause the phenomenon drag reduction was introduced.Drag reduction be defined as the increase in pumpability of a fluid caused by the add...
