Comparison of computational codes for direct numerical simulations of turbulent Rayleigh-Bénard convection
Gijs L. Kooij, Mikhail A. Botchev, Edo M. A. Frederix +7
Computational codes for direct numerical simulations of Rayleigh-Bénard (RB) convection are compared in terms of computational cost and quality of the solution. As a benchmark case…
Translational and rotational dynamics of a large buoyant sphere in turbulence
Varghese Mathai, Matthijs W. M. Neut, Erwin P. van der Poel +1
We report experimental measurements of the translational and rotational dynamics of a large buoyant sphere in isotropic turbulence. We introduce an efficient method to simultaneous…
Flow states in two-dimensional Rayleigh-Bénard convection as a function of aspect-ratio and Rayleigh number
Erwin P. van der Poel, Richard J. A. M. Stevens, Kazuyasu Sugiyama +1
In this numerical study on two-dimensional Rayleigh-Bénard convection we consider in aspect ratio samples. We focus on several case…
