The Ring of Brownian motion: The good, the bad and some simply silly

چکیده

Since the turn of the 20-th century Brownian noise has continuously disclosed a rich variety of phenomena in and around physics. The understanding of this jittering motion of suspended microscopic particles has undoubtedly helped to reinforce and substantiate those pillars on which the basic modern physical theories are resting: Its formal description provided the key to great achievements in statistical mechanics, the foundations of quantum mechanics and also astrophysical phenomena, to name but a few. -Brownian motion determines the rate limiting step in most transport phenomena via escape events that help to overcome obstructing bottlenecks [1], does trigger firing events of neurons and in ion channels or, more generally, induces oscillatory dynamics in excitable media [2]. More recent progress of Brownin motion theory involves (i) the description of relativistic Brownian motion and its impact for relativistic thermodynamics [3], or (ii) its role for fluctuation theorems and symmetry relations that constitute the fulcrum of the recent developments of nonequilibrium thermodynamics beyond the linear response regime [4].

The Ring of Brownian Motion: the good, the bad and the simply silly

In this plenary talk I give an account on the blossoming role that Brownian motion Theory and Experiment played and still keeps doing so in germinating and advancing several, partially diverse physical disciplines. Although the use of Brownian motion concepts generally most favorably impacted those scientific areas there are also some abuses where the application of such concepts may not descri...

Effects of Brownian motion and Thermophoresis on MHD Mixed Convection Stagnation-point Flow of a Nanofluid Toward a Stretching Vertical Sheet in Porous Medium

This article deals with the study of the two-dimensional mixed convection magnetohydrodynamic (MHD) boundary layer of stagnation-point flow over a stretching vertical plate in porous medium filled with a nanofluid. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis in the presence of thermal radiation. The skin-friction coefficient, Nusselt number an...

The effect of various conductivity and viscosity models considering Brownian motion on nanofluids mixed convection flow and heat transfer

 In this paper the effect of using various models for conductivity and viscosity considering Brownian motion of nanoparticles is investigated. This study is numerically conducted inside a cavity full of Water-Al2O3 nanofluid at the case of mixed convection heat transfer. The effect of some parameters such as the nanoparticle volume fraction, Rayleigh, Richardson and Reynolds numbers has been ex...

The Effects of Different SDE Calculus on Dynamics of Nano-Aerosols Motion in Two Phase Flow Systems

Langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. The Brownian motion generated from molecular bombardment was taken as a Wiener stochastic process and approximated by a Gaussian white noise. Euler-Maruyama method was used to solve the Langevin equation numerically. The accuracy of Brownian simulation was checked by performing a series of simulati...
