Improved viscosity-concentration equation for emulsions of nearly spherical droplets [PDF]
arXiv, 2009 We propose an improved viscosity model accounting for experiments of emulsions of two immiscible liquids at arbitrary volume fractions and low shear rates. The model is based on a recursive-differential method formulated in terms of the appropriate scaling variable which emerges from an analysis of excluded volume effects in the system.

An exploration of viscosity models in the realm of kinetic theory of liquids originated fluids
Results in Physics, 2017 The preeminent perspective of this article is to study flow of an Eyring Powell fluid model past a penetrable plate. To find the effects of variable viscosity on fluid model, continuity, momentum and energy equations are elaborated.

On the dissipation layer of radial bearings
International Journal of Mathematics and Mathematical Sciences, 1988 The dissipation boundary layer of certain radial bearings is identified. It is shown that, under certain conditions, the temperature outside this layer is constant.

Existence of solutions for an Oldroyd model of viscoelastic fluids
Electronic Journal of Differential Equations, 2009 In this paper we investigate the unilateral problem for an Oldroyd model of a viscoelastic fluid. Using the penalty method, Faedo-Galerkin's approximation, and basic result from the theory of monotone operators, we establish the existence of weak ...

On almost periodic viscosity solutions to Hamilton-Jacobi equations [PDF]
arXiv, 2017 We establish that a viscosity solution to a multidimensional Hamilton-Jacobi equation with Bohr almost periodic initial data remains to be spatially almost periodic and the additive subgroup generated by its spectrum does not increase in time. In the case of one space variable and a non-degenerate hamiltonian we prove the decay property of almost ...

Viscosity Solutions in Non-commutative Variables
Motivated by parallels between mean field games and random matrix theory, we develop stochastic optimal control problems and viscosity solutions to Hamilton-Jacobi equations in the setting of non-commutative variables. Rather than real vectors, the inputs to the equation are tuples of self-adjoint operators from a tracial von Neumann algebra.
