Direct numerical simulations of Taylor--Couette turbulence: the effect of sand grain roughness
Pieter Berghout, Xiaojue Zhu, Daniel Chung +3
Progress in roughness research, mapping any given roughness geometry to its fluid dynamic behaviour, has been hampered by the lack of accurate and direct measurements of skin-frict…
Transition to the ultimate regime in two-dimensional Rayleigh-Bénard convection
Xiaojue Zhu, Varghese Mathai, Richard J. A. M. Stevens +2
The possible transition to the so-called ultimate regime, wherein both the bulk and the boundary layers are turbulent, has been an outstanding issue in thermal convection, since th…
Turbulent thermal superstructures in Rayleigh-Bénard convection
Richard J. A. M. Stevens, Alexander Blass, Xiaojue Zhu +2
We report the observation of superstructures, i.e.\ very large-scale and long living coherent structures in highly turbulent Rayleigh-Bénard convection up to Rayleigh . We…
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…
