Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Lattice Boltzmann Simulation of Collision between 2D Circular Particles Suspension in Couette Flow
Abstract and Applied Analysis, 2013 Collision between 2D circular particles suspension in Couette flow is simulated by using multiple-relaxation-time based lattice Boltzmann and direct forcing/fictitious domain method in this paper.

A direct numerical simulation display of the rotational frame preference of turbulence
AIP Advances, 2023 An elementary observation of a laminar cylindrical Poiseuille–Couette flow profile reveals no distinction in the parabolic streamwise profile, from one without a cross-stream flow, in whatever reference frame the observation is made.

A Geometric Characterization of Steady Laminar Flow
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Hydromagnetic instability in plane Couette flow
Physical Review E, 2007 We study the stability of a compressible magnetic plane Couette flow and show that compressibility profoundly alters the stability properties if the magnetic field has a component perpendicular to the direction of flow. The necessary condition of a newly found instability can be satisfied in a wide variety of flows in laboratory and astrophysical ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Wildlife Letters, EarlyView.Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

International Journal of Cosmetic Science, EarlyView.Hydrophobic natural eutectic solvents can function as structural oil phase substitutes in creams prepared by low‐energy processes, enabling sustainable, regulation‐compliant formulations with desirable sensory profiles. Abstract Objective This work evaluates whether hydrophobic natural eutectic solvents can replace the conventional oil phase in ...

International Journal of Cosmetic Science, EarlyView.Dual asymmetric centrifugation (DAC) enables the preparation of stable cosmetic emulsions and structured creams with physicochemical, rheological and textural properties comparable to those of conventional processes. At larger scales, DAC also offers competitive energy efficiency by avoiding heating steps, supporting more sustainable cosmetic ...
