Alternative derivation of the Feigel effect and call for its experimental verification
, 2011 A recent theory by Feigel [Phys. Rev. Lett. {\bf 92}, 020404 (2004)] predicts the finite transfer of momentum from the quantum vacuum to a fluid placed in strong perpendicular electric and magnetic fields.

Navier-Stokes Flow in Cylindrical Elastic Tubes
Journal of Applied Fluid Mechanics, 2015 Analytical expressions correlating the volumetric flow rate to the inlet and outlet pressures are derived for the time-independent flow of Newtonian fluids in cylindrically-shaped elastic tubes using a one-dimensional Navier-Stokes flow model with two ...

Cyclic motion and inversion of surface flow direction in a dense polymer brush under shear
, 2007 Using molecular simulations, we study the properties of a polymer brush in contact with an explicit solvent under Couette and Poiseuille flow. The solvent is comprised of chemically identical chains.

Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers
Small, EarlyView.The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Analysis of flow rates in cracked reinforced concrete
Structural Concrete, EarlyView.Abstract According to Eurocode 2, part 3, autogenous self‐healing of separation cracks with a width ≤0.20 mm can be considered under certain hydraulic conditions. However, practical experience shows that healing does not always reliably occur even when this crack width is maintained.

Slip flow in an annular sector duct using radial eigenfunctions
Theoretical and Applied Mechanics Letters, 2014 The fully developed slip flow in an annular sector duct is solved by expansions of eigenfunctions in the radial direction and boundary collocation on the straight sides. The method is efficient and accurate. The flow field for slip flow differs much from

On pressure and velocity flow boundary conditions and bounceback for the lattice Boltzmann BGK model
, 1996 Pressure (density) and velocity boundary conditions inside a flow domain are studied for 2-D and 3-D lattice Boltzmann BGK models (LBGK) and a new method to specify these conditions are proposed.

POISEUILLE FLOW INSTABILITIES IN NEMATICS
Le Journal de Physique Colloques, 1975 We have extended our study of shear flow instabilities in nematics, aligned perpendicular to the velocity and velocity gradient, to the plane Poiseuille flow case. We recover the homogeneous as well as the roll instability modes. The non-uniform anisotropic stress tensor gives rise to body forces which deflect the flow lines and couple with the ...
