[LIBRO][B] Partial differential equations in anisotropic Musielak-Orlicz spaces

Anisotropic and inhomogeneous spaces, which are at the core of the present study, may
appear exotic at first. However, the reader should abandon this impression once they realize …

A review of implicit algebraic constitutive relations for describing the response of nonlinear fluids

Large data existence theory for three-dimensional unsteady flows of rate-type viscoelastic fluids with stress diffusion

M Bathory, M Bulíček, J Málek - Advances in Nonlinear Analysis, 2020 - degruyter.com
We prove that there exists a weak solution to a system governing an unsteady flow of a
viscoelastic fluid in three dimensions, for arbitrarily large time interval and data. The fluid is …

Electrokinetic energy conversion of fluids with pressure-dependent viscosity in nanofluidic channels

Y Jian - International Journal of Engineering Science, 2022 - Elsevier
In this paper, electrokinetic flow of Newtonian fluids with pressure-dependent viscosity
through a nanoslit is investigated. Under the assumption of unidirectional steady flow, taking …

[HTML][HTML] On determining Navier's slip parameter at a solid boundary in flows of a Navier–Stokes fluid

J Málek, KR Rajagopal - Physics of Fluids, 2024 - pubs.aip.org
While the assumption of the “no-slip” condition at a solid boundary is unquestioningly
applied to study the flow characteristics of a Navier–Stokes fluid, there was considerable …

[HTML][HTML] Nonlinear Reynolds equation for hydrodynamic lubrication

T Gustafsson, KR Rajagopal, R Stenberg… - Applied Mathematical …, 2015 - Elsevier
We derive a novel and rigorous correction to the classical Reynolds lubrication
approximation for fluids with viscosity depending upon the pressure. Our analysis shows that …

Flow of fluids with pressure-and shear-dependent viscosity down an inclined plane

KR Rajagopal, G Saccomandi… - Journal of Fluid …, 2012 - cambridge.org
In this paper we consider a fluid whose viscosity depends on both the mean normal stress
and the shear rate flowing down an inclined plane. Such flows have relevance to …

Large data analysis for Kolmogorov's two-equation model of turbulence

M Bulíček, J Málek - Nonlinear Analysis: Real World Applications, 2019 - Elsevier
Kolmogorov seems to have been the first to recognize that a two-equation model of
turbulence might be used as the basis of turbulent flow prediction. Nowadays, a whole …
