Statistics and spectral analysis of turbulent duct flows with flexible and rigid polymer solutions
Rodrigo S. Mitishita, Gwynn J. Elfring, Ian A. Frigaard
We present an experimental investigation of turbulent drag reduction with flexible and rigid polymer solutions. The flexible polymer is partially hydrolyzed polyacrylamide (HPAM) a…
Fully turbulent flows of viscoplastic fluids in a rectangular duct
Rodrigo S. Mitishita, Jordan A. MacKenzie, Gwynn J. Elfring +1
Turbulent flows of viscoplastic fluids at high Reynolds numbers have been investigated recently with direct numerical simulations (DNS) but experimental results have been limited.…
Turbulent drag reduction of viscoelastic wormlike micellar gels
Rodrigo S. Mitishita, Gwynn J. Elfring, Ian A. Frigaard
Long-chained, viscoelastic surfactant solutions (VES) have been widely employed in the oil and gas industry, particularly in hydraulic fracturing and gravel-packing operations, whe…
Rheology of Wormlike Micellar Gels Formed By Long-Chained Zwitterionic Surfactants
Ronak Gupta, Rodrigo Mitishita, Ian A. Frigaard +1
Long-chained surfactant solutions have found widespread use in the oil and gas industry due to a host of attractive properties. In this paper, we characterize one such commercially…
