A Direct Assessment of Langmuir Turbulence Parameterizations in Idealized Coastal Merging Boundary Layers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Langmuir turbulence affects turbulent mixing in the ocean boundary layers and its effects require parameterizations in ocean circulation models. Most existing Langmuir turbulence parameterizations focus on the surface boundary layer in open oceans.

Taylor-Couette Flow Instabilities in Journal Bearings [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2010
In industry, flow instabilities are important in journal bearings at high rotational speeds. For inviscid flows between two rotating coaxial cylinders, an instability criterion was introduced by Taylor-Couette.

Validation of a Novel Self‐Consistent Mean‐Field Approach and Corresponding Equation to Describe the Concentration Dependence of the Viscosity of Polymer Solutions

Advances in Polymer Technology, Volume 2026, Issue 1, 2026.
Polymer composites and polymer solutions are extensively studied in polymer science. For polymer solutions, the viscosity is a key property relevant for many applications, where the intrinsic viscosity plays an important role. A recent self‐consistent theoretical description revealed a novel equation relating solution viscosity to concentration and ...

Spectral method for identification of flow regimes in a Couette-Taylor annular flow [PDF]

E3S Web of Conferences
The paper presents a study of flow structure in an annular flow of the Couette-Taylor system, employing spectral analysis of moment of resistance and radial dynamic pressure pulsations. Experiments were conducted on a model featuring a single annular gap,

Analog of astrophysical magnetorotational instability in a Couette-Taylor flow of polymer fluids [PDF]

Physical Review E, 2009
We report experimental observation of an instability in a Couette-Taylor flow of a polymer fluid in a thin gap between two coaxially rotating cylinders in a regime where their angular velocity decreases with the radius while the specific angular momentum increases with the radius.

Numerical Investigation of Stick–Slip Flow in Shear‐Thinning and Shear‐Thickening Power‐Law Inelastic Fluids

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
This research focuses on studying an incompressible, non‐Newtonian fluid within an axisymmetric straight channel in cylindrical coordinates, divided under the influence of two zones, subject to two boundary conditions: one without slip and the other with slip.

Magnetorotational-type Instability in Couette-Taylor Flow of a Viscoelastic Polymer Liquid [PDF]

Physical Review Letters, 2008
We describe an instability of viscoelastic Couette-Taylor flow that is directly analogous to the magnetorotational instability (MRI) in astrophysical magnetohydrodynamics, with polymer molecules playing the role of magnetic field lines. By determining the conditions required for the onset of instability and the properties of the preferred modes, we ...
