Friction reducers (FRs) play a vital role in large-displacement shale hydraulic fracturing. This
paper reviews the drag reduction (DR) mechanism of FRs, its development and application …

The flow of fluids in channels, pipes, or ducts, as in any other wall-bounded flow (like water
along the hulls of ships or air on airplanes) is hindered by a drag, which increases manyfold …

We present an experimental study of a low-Reynolds number shear flow between two
surfaces, one of which has a regular grooved texture augmented with a superhydrophobic …

Stream‐wise velocity‐gradients associated with extensional flows arise in thinning liquid
necks spontaneously formed during jetting, printing, coating, spraying, atomization, and …

Bubbly turbulent Taylor–Couette (TC) flow is globally and locally studied at Reynolds
numbers of. We conclude that bubble deformability is a relevant mechanism behind the …

Flow control technologies have been used in the past century to control fluid flows. This text
presents the current state of the art in emerging modern flow control technologies and …

We use direct numerical simulations to study homogeneous and isotropic turbulent flows of
dilute polymer solutions at high Reynolds and Deborah numbers. We find that for small …

Thanks to direct observation and manipulation of DNA in micro/nanofluidic devices, we are
now able to elucidate the relationship between the polymer microstructure and its …

We report viscosity data of nonentangled sodium polystyrene sulfonate (NaPSS) in salt-free
aqueous solution as a function of polymer concentration (c) and degree of polymerization …

The flow of polymer solutions is examined in a flow geometry where a jet is used to inject the
viscoelastic solution into a cylindrical tube. We show that this geometry allows for the …
