WebSchmalzl et al. found that at moderate Rayleigh numbers, with Prandtl number greater than unity and rigid boundary conditions the behaviour of Rayleigh-Bénard convection was similar in two and three dimensional systems. van der Poel et al. extended this result to higher Rayleigh numbers and found that the global properties of the flow, including the heat … WebRayleigh distribution is a continuous probability distribution for positive-valued random variables. The data can be given by the mean value and a lower bound, or by a parameter …

Webis the ratio of the refractive index of the particle to that of the surrounding medium. Therefore, in the Rayleigh regime, the scattering efficiency is simply proportional to x 4. In the optical scattering regime, Q eff → ≈ 2. However, in the intermediate regime, the scattering efficiency is seen to oscillate as the size parameter increases. WebNumerical simulations are used to probe Rayleigh–Darcy convection in fluid-saturated porous media towards the ultimate regime. The present three-dimensional dataset, up to Rayleigh–Darcy number $\textit {Ra}=8\times 10^4$, suggests that the appropriate scaling of the Nusselt number is $\textit {Nu}=0.0081\textit {Ra}+0.067\textit {Ra}^{0.61}$, fitting … WebMay 30, 2012 · Well-resolved direct numerical simulations of 2D Rayleigh-B\'enard convection in a porous medium are presented for Rayleigh numbers $\mathrm{Ra}\ensuremath{\le}4\ifmmode\times\else\texttimes\fi{}{10}^{4}$ which ...

Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance … See more In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, John Tyndall discovered that bright light scattering off nanoscopic particulates was … See more The expression above can also be written in terms of individual molecules by expressing the dependence on refractive index in terms of the molecular polarizability α, proportional to the dipole moment induced by the electric field of the light. In this case, … See more The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the … See more Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered materials with microscopic variations of density and refractive index. These give rise to energy losses due to the … See more The size of a scattering particle is often parameterized by the ratio where r is the particle's radius, λ is the wavelength of the light and x is a dimensionless parameter See more When the dielectric constant $${\displaystyle \epsilon }$$ of a certain region of volume $${\displaystyle V}$$ is different from the average dielectric constant of the medium $${\displaystyle {\bar {\epsilon }}}$$, then any incident light will be … See more Rayleigh scattering is also an important mechanism of wave scattering in amorphous solids such as glass, and is responsible for acoustic wave damping and phonon … See more WebAug 23, 2024 · The effects of electron nonlocal heat transport (NLHT) on the two-dimensional single-mode ablative Rayleigh–Taylor instability ... “ Measurement of a dispersion curve for linear-regime Rayleigh-Taylor growth rates in laser-driven planar targets,” Phys.
