Rayleigh regime
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 … 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.
