Flow states and heat transport in Rayleigh--Bénard convection with different sidewall boundary conditions
Philipp Reiter, Xuan Zhang, Olga Shiskina
This work addresses the effects of different thermal sidewall boundary conditions on the formation of flow states and heat transport in two- and three-dimensional Rayleigh--Bénard…
Connecting wall modes and boundary zonal flows in rotating Rayleigh--Bénard convection
Robert E. Ecke, Xuan Zhang, Olga Shishkina
Using direct numerical simulations, we study rotating Rayleigh-Bénard convection in a cylindrical cell for a broad range of Rayleigh, Ekman, and Prandtl numbers from the onset of w…
Boundary zonal flows in rapidly rotating turbulent thermal convection
Xuan Zhang, Robert E. Ecke, Olga Shishkina
Recently, in Zhang et al. (2020), it was found that in rapidly rotating turbulent Rayleigh-Bénard convection (RBC) in slender cylindrical containers (with diameter-to-height aspect…
Generation of zonal flows in convective systems by travelling thermal waves
Philipp Reiter, Xuan Zhang, Rodion Stepanov +1
This work addresses the effect of travelling thermal waves applied at the fluid layer surface, on the formation of global flow structures in 2D and 3D convective systems. For a bro…
Boundary Zonal Flow in Rotating Turbulent Rayleigh-Bénard Convection
Xuan Zhang, Dennis P. M. van Gils, Susanne Horn +7
For rapidly rotating turbulent Rayleigh--Bénard convection in a slender cylindrical cell, experiments and direct numerical simulations reveal a boundary zonal flow (BZF) that repla…
Instabilities in extreme magnetoconvection
Oleg Zikanov, Yaroslav Listratov, Xuan Zhang +1
Thermal convection in an electrically conducting fluid (for example, a liquid metal) in the presence of a static magnetic field is considered in this chapter. The focus is on the e…
Mixed convection in a downward flow in a vertical duct with strong transverse magnetic field
Xuan Zhang, Oleg Zikanov
The downward flow in a vertical duct with one heated and three thermally insulated walls is analyzed numerically using the two-dimensional approximation valid in the asymptotic lim…
