摘要

In the present research, Sodium Lauryl Ether Sulphate (SLES) was investigated not only as a drag reducing agent for two phase system (solid-liquid). It is desired to divide the present study into two consequence steps which are, the addition of small amounts of solid particles that can be suspended in liquid used (kerosene), these suspensions may be used as drag reducing agents, then the other step is established by the addition of small quantities of certain surfactant to the suspension transported. The results showed that, percentage drag reduction (Dr%) increases by increasing the suspended particles concentration, suspended particle size, Surfactant concentration and solution velocity (Reynolds No.). Maximum Dr% of 34% was obtained using 1500 ppm of Sand powder suspended in Kerosene and pumped within maximum flow rate. This maximum percentage was increased to 44% by the addition of SLES with concentration up to 600 ppm with the same conditions above.
