The Effect of Viscous Dissipation and Variable Properties on Nanofluids Flow in Two Dimensional Microchannels

Laminar two dimensional forced convective heat transfer of Al2O3 –water nanofluid in a horizontal microchannel has been studied numerically, considering axial conduction, viscous dissipation and variable properties effects. The existing criteria in the literature for considering viscous dissipation in energy equation are compared for different cases and the most proper one is applied for the re...

Two-dimensional Brownian vortices

We introduce a stochastic model of two-dimensional Brownian vortices associated with the canonical ensemble. The point vortices evolve through their usual mutual advection but they experience in addition a random velocity and a systematic drift generated by the system as a whole. The statistical equilibrium state of this stochastic model is the Gibbs canonical distribution. We consider a single...

Vortices in Two-dimensional Nematics

Abstract. We study a two-dimensional model describing spatial variations of orientational ordering in nematic liquid crystals. In particular, we show that the spatially extended OnsagerMaier-Saupe free energy may be decomposed into Landau-de Gennes-type and relative entropy-type contributions. We then prove that in the high concentration limit the states of the system display characteristic vor...

Critical anisotropies of two-dimensional magnetic vortices

Critical easy-plane anisotropies where in-plane magnetic vortices in two-dimensional Heisenberg models are stabilized are determined precisely on square, hexagonal and triangular lattices, by finding the anisotropy that leads to a zero frequency mode.

Dynamics of Vortices in Two-Dimensional Magnets

Theories, simulations and experiments on vortex dynamics in quasi-two-dimensional magnetic materials are reviewed. These materials can be modelled by the classical two-dimensional anisotropic Heisenberg model with XY (easy-plane) symmetry. There are two types of vortices, characterized by their polarization (a second topological charge in addition to the vorticity): Planar vortices have Newtoni...
