Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The hydraulic transport of solid mineral particles in a vertical pipe is used in many engineering applications, for example in ocean mining. Tested pipe friction data of solid- liquid two-phase flow on vertical pipes, both stationary and horizontally vibrating, were analyzed and expressed in dimensionless formula to show the pipe frictional factor in relation with Reynolds number. It was shown that the solid- liquid two-phase flow produces higher friction than pure water flow when Reynolds number is less than about , the lower Reynolds number is the difference is higher. It was also shown that for the vibrating pipe, the friction factor of the pure water does not change with the frequency of the pipe vibration. The solid-liquid two-phase pipe flow´s friction factor in the vibrating pipe, however, is not only higher than pure flow´s, but also higher than the friction factor of stationary two-phase pipe flow. The increase is more when the vibrating frequency is higher.
