The drag reducing and degradation characteristics of Dowell-APE and Calgon TRO-513 materials dispersed in hexane were studied by measuring the frictional losses as a function of time under turbulent flow conditions in a recycle loop experimental…
The frictional dragreducing characteristics of Shell PEP-4 and Conoco CDR polymer-hexane solutions in turbulent smooth tube flow were investigated. The effects of flow time, polymer concentration, Reynolds number and tube diameter on drag reduction…
