solution is experimentally investigated inside a circular microchannel of 200 μm.
Displacement is commonly encountered in many industrial applications, from cleaning and
decontamination to enhanced oil recovery. In this study, a pure viscoelastic fluid with no
shear-thinning properties (known as Boger fluid) made up of polyethylene oxide,
polyethylene glycol, and zinc chloride is used to displace an immiscible organic liquid …
