Non-Oberbeck-Boussinesq effects in turbulent thermal convection in ethane close to the critical point
Guenter Ahlers, Enrico Calzavarini, Francisco Fontenele Araujo +4
As shown in earlier work (Ahlers et al., J. Fluid Mech. 569, p.409 (2006)), non-Oberbeck Boussinesq (NOB) corrections to the center temperature in turbulent Rayleigh-Benard convect…
Wind reversals in turbulent Rayleigh-Benard convection
Francisco Fontenele Araujo, S. Grossmann, D. Lohse
The phenomenon of irregular cessation and subsequent reversal of the large-scale circulation in turbulent Rayleigh-Bénard convection is theoretically analysed. The force and therma…
Variable survival exponents in history-dependent random walks: hard movable reflector
Ronald Dickman, Francisco Fontenele Araujo, Daniel ben-Avraham
We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for history-dependent random walks, and analyze a new example, the hard movable part…
Asymptotic analysis of a random walk with a history-dependent step length
Ronald Dickman, Francisco Fontenele Araujo, Daniel ben-Avraham
We study an unbiased, discrete time random walk on the nonnegative integers, with the origin absorbing. The process has a history-dependent step length: the walker takes steps of l…
