摘要：
In this study the effect of the presence of a drag reducing agent (DRA) on the pressure drop in cocurrent horizontal rough pipes carrying annular flow of air and crude oil is investigated. An experimental Set-LIP is constructed. The test section of the experimental set-tip consists of two rough pipes of galvanized iron, 8.8m long and having 2.54cm and 1.27cm ID. The DRA applied is a polyalpha-olefin (polyisobutylene). The pressure drop, both in the presence and the lack of DRA, has been calculated using the experimental data obtained. The results show that the addition of DRA could be effective LIP to certain closes of DRA, after which, the pressure drop is kept constant. A percentage drag reduction of about 45 is observed at some experimental conditions.
