Viscosity driven variations in slot die coating of nanocellulosic barrier layers
AIChE Journal, EarlyView.Abstract A suitable candidate for applying nanocellulose on paper as packaging material is slot die coating, but a complex rheological behavior makes process optimization challenging. In this work, coating windows of nanocellulosic suspensions modeled as Casson fluids with different viscosities have been determined with computational fluid dynamics ...

A Regularity Criterion for the Navier-Stokes Equations in the Multiplier Spaces
Abstract and Applied Analysis, 2012 We exhibit a regularity condition concerning the pressure gradient for the Navier-Stokes equations in a special class. It is shown that if the pressure gradient belongs to 𝐿2/(2−𝑟)̇𝐻((0,𝑇);ℳ(𝑟(ℝ3̇𝐻)→−𝑟(ℝ3))), where ̇𝐻ℳ(𝑟(ℝ3̇𝐻)→−𝑟(ℝ3)) is the multipliers ...

Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid
Annalen der Physik, EarlyView.The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

Governing equations of fluid mechanics in physical curvilinear coordinate system
Electronic Journal of Differential Equations, 1998 This paper presents the development of unsteady three-dimensional incompressible Navier-Stokes and Reynolds-averaged Navier-Stokes equations in an unsteady physical curvilinear coordinate system. It is demonstrated that the numerical simulations based on
