PCT No. PCT/GB86/00224 Sec. 371 Date Dec. 10, 1986 Sec. 102(e) Date Dec. 10, 1986 PCT Filed Apr. 24, 1986 PCT Pub. No. WO86/06311 PCT Pub. Date Nov. 6, 1986.Abrasive fluid, which includes abrasive material and a carrier fluid, is transported through a conduit with minimum wear by directing the abrasive material along the center of the flow channel within the conduit, accelerating the carrier fluid and entraining the abrasive material within the accelerated carrier fluid. A conduit for performing this method includes a flow channel, means (9) adjacent its upstream section (1) for directing abrasive material along the center of the flow channel, a section (2) of reduced cross-section for accelerating carrier fluid in the flow channel and a down-stream section (3) for accelerating the abrasive material at the center of the flow channel due to entrainment with the accelerated carrier fluid. |
