Critical Rayleigh number in Rayleigh-Bénard convection [PDF]
Quarterly of Applied Mathematics, 2009 Summary: The Rayleigh-Bénard convection is a classical problem in fluid dynamics. In the presence of rigid boundary condition, we identify the critical Rayleigh number \( R_{a}^{\ast }\) by a reduced variational problem. We prove nonlinear asymptotic stability for motionless steady states for \( R_{a}R_{a}^{\ast }.\) The dynamic of such instability is ...

Prandtl and Rayleigh numbers dependences in Rayleigh-Bénard convection [PDF]
Europhysics Letters (EPL), 2002 Using low-temperature gaseous helium close to the critical point, we investigate the Prandtl-number dependence of the effective heat conductivity (Nusselt number) for a 1/2 aspect ratio Rayleigh-Benard cell. Very weak dependence is observed in the range 0.7 < Pr < 21; 2 × 108 < Ra < 2 × 1010: the absolute value of the average logarithmic slope δ = (∂ln

The 2008 Election: A Preregistered Replication Analysis
Statistics and Public Policy, 2017 We present an increasingly stringent set of replications, a multilevel regression and poststratification analysis of polls from the 2008 U.S. presidential election campaign, focusing on a set of plots showing the estimated Republican vote share for ...

Moist turbulent Rayleigh-Benard convection with Neumann and Dirichlet boundary conditions
, 2012 Turbulent Rayleigh-Benard convection with phase changes in an extended layer between two parallel impermeable planes is studied by means of three-dimensional direct numerical simulations for Rayleigh numbers between 10^4 and 1.5\times 10^7 and for ...

Simulation of the growth of the 3D Rayleigh-Taylor instability in Supernova Remnants using an expanding reference frame [PDF]
, 2010 Context: The Rayleigh-Taylor instabilities generated by the deceleration of a supernova remnant during the ejecta-dominated phase are known to produce finger-like structures in the matter distribution which modify the geometry of the remnant.
