Atmospheric Ekman Flows with Variable Eddy Viscosity [PDF]
Boundary-Layer Meteorology, 2018 We revisit the classical problem of the behaviour of the wind in the steady atmospheric Ekman layer. We show, for general variable eddy viscosities, that in the Northern Hemisphere the time-averaged ageostrophic wind profile always decays in magnitude and turns clockwise with increasing height.

On variable viscosity and enhanced dissipation
Nonlinearity, 2023 Abstract In this article we consider the two-dimensional Navier–Stokes equations with variable viscosity depending on the vertical position. As our main result we establish linear enhanced dissipation near the non-affine stationary states replacing Couette flow. For instance, these shear flows may grow exponentially.

Incorporating variable viscosity in vorticity-based formulations for Brinkman equations [PDF]
, 2019 In this brief note, we introduce a non-symmetric mixed finite element formulation for Brinkman equations written in terms of velocity, vorticity and pressure with non-constant viscosity.

3-D Convection With Variable Viscosity [PDF]
Geophysical Journal International, 1991 Accepted 1990 September 6. Received 1990 July 16; in original form 1990 May 3 SUMMARY report numerical calculations for 3-D convection with variable viscosity. A hybrid spectral and finite difference method is used. The coupling of modes in the equation of motion, which is caused by lateral viscosity variations, is treated iteratively.

Mathematical Modelling and Analysis, 2015 We consider methods for the numerical simulations of variable density incompressible fluids, modelled by the Navier–Stokes equations. Variable density problems arise, for instance, in interfaces between fluids of different densities in multiphase flows ...

Effect of lubricant compressibility and variable viscosity on the performance of three-lobe journal bearing [PDF]
Archive of Mechanical Engineering, 2022 Different configurations of journal bearings have been extensively used in turbomachinery and power generating equipment. Three-lobe bearing is used due to its lower film temperature and stable operation.

Cooperative Shear Model for the Rheology of Glass-Forming Metallic Liquids [PDF]
, 2006 A rheological law based on the concept of cooperatively sheared flow zones is presented, in which the effective thermodynamic state variable controlling flow is identified to be the isoconfigurational shear modulus of the liquid.
