WebThe onset of Rayleigh–Benard (RB) convection in a fluid confined between´ horizontal planes and heated from below is a classical problem in hydrodynamic stability theory and has accordingly been studied extensively (Chandrasekhar 1961; Koschmieder 1993). Most of these analyses have been carried out within the WebMay 1, 2024 · Example for such systems are dense water over oil (liquid–liquid), or water over air(gas–liquid). The original Rayleigh's paper deals with the dynamics and density variations. For example, density variations according to the bulk modulus (see section 4.3.3.2) are always stable but unstable of the density is in the reversed order.
WebJan 30, 2003 · In the case of an isothermal liquid bridge between circular disks without any axial acceleration, g=0, having cylindrical volume V*=πR 2 L (its interface would then be a right circular cylinder), the well-known Rayleigh stability limit holds. In this case the liquid column becomes unstable when its length is larger than its circumference (L>2πR).
WebThe limit value ${\ensuremath{\xi}}_{c}$, below which squares are stable, decreases with increasing shear-thinning effects. This is related to the fact that shear-thinning effects increase the nonlinear interactions between sets of rolls that constitute the square patterns [M. Bouteraa et al., J. Fluid Mech. 767, 696 (2015)]. WebWe consider here the form and stability of fluid jets falling under the influence of gravity. ...
