Therefore, the mobility process of the nodes which encountered the destination based on Brownian motion is studied in this section.
The numerical solutions are obtained using the above numerical scheme for some values of the governing parameters, namely, the magnetic parameter (M), the wall mass transfer parameter (S), the Prandtl number (Pr), the Lewis number (Le), Brownian motion parameter (Nb), and thermophoresis parameter (Nt).
Murshed and Nieto de Castro [12] demonstrated that Brownian motion plays a significant role in enhancing the thermal conductivity of nanofluids especially at a low concentration of nanoparticles or their smaller sizes.
where Pr is the Prandtl number, Le is the Lewis number, Nb is the Brownian motion parameter, and Nt is the thermophoresis parameter, which are defined as follows:
The Simulation of Brownian Motion Effect on the Effective Thermal Convection
where prime denotes differentiation with respect to q and Pr, Le, [N.sub.b], [N.sub.t], and [epsilon] denote Prandtl number, Lewis number, Brownian motion, thermophoresis, and stretching parameter, respectively.
A microscope with a camera attached is fixed on the particles as Brownian motion pushes them back and forth, and computer software tracks the motions of up to eight of the particles.
Brownian motion is a stochastic process Bt having continuous sample paths, as well as its independent increment [B.sub.t] - [B.sub.s], s < t, following a normal distribution N (0, t--s).
where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is a linear independent system of Brownian motion in a probability space {[OMEGA], F, P}, O is a bounded and open subset of [R.sup.d], d [greater than or equal to] 1, with smooth boundary [partial derivative]O.
Chapter topics include complexity and entropy, thermodynamics, the thermodynamics of phase transitions, equilibrium statistical mechanics, Brownian motion and fluctuation- dissipation, hydrodynamics, transport coefficients, and nonequilibrium phase transitions.
Nanoparticle tracking analysis (NTA), invented by Bob Carr, now the CTO of NanoSight, Amesbury, UK, is the first technology that can directly track the Brownian motion that makes DLS work.
We now extend the definition of Brownian motion from R, which can be found in [7] and [8], to any time scale T as follows.
The researchers fabricated a ratcheted microgear with slotted spokes, something quite similar to what other groups have built to capture Brownian motion. They immersed this gear set into a bath populated with a common bacteria.
Note that Brenner's equation accounts for (rotary) Brownian motion via the rotary Peclet number (rotary diffusion coefficient).
