Experimental study on high-pressure rheology of water/crude oil emulsion in the presence of methane

Transient Free Convection Mass Transfer of Second-grade Fluid Flow with Wall Transpiration

“…In common terms, this means the fluid continues to flow, regardless of the forces acting on it. For example, all gases are Newtonian, as are most common liquids such as water, hydrocarbons, oils, and air [3]. However, fluids in which shear stress is not proportional to the velocity gradient are called non-Newtonian fluids [4].…”

High Pressure Rheological Behavior of 1-Ethyl-3-methylimidazolium n-Hexylsulfate and Trihexyl(tetradecyl)phosphonium Tris(pentafluoroethyl)trifluorophosphate

“…Martı́nez-Boza and his collaborators − performed rheological studies on used motor oil/vacuum residue blends, bitumens, heavy oils, inverted-emulsion oil muds, and drilling fluids with two controlled stress rheometers, RheoStress RS600 from Haake Gbr and MARS II, from Thermo Scientific, using a coaxial cylinder and double helical ribbon geometries. Sun et al characterized a water/crude oil emulsion in the presence of methane with an Anton Paar (Graz, Austria) MCR302 rheometer, the temperature of which can be controlled between 123.15 and 1273.15 K and up to 15 MPa . Finally, modified Couette geometries have been recently proposed by Pandey et al to characterize forming gas hydrates.…”

In this work we have undertaken the setup of a new device for rheological characterization at high pressure.…”
