Spontaneous generation of helical flows by salt fingers
Adrian E. Fraser, Adrian van Kan, Edgar Knobloch +2
We study the dynamics of salt fingers in the regime of slow salinity diffusion (small inverse Lewis number) and strong stratification (large density ratio), focusing on regimes rel…
Traveling spatially localized convective structures in an inclined porous medium
Zhiwei Dave Li, Chang Liu, Adrian van Kan +1
Multiple stationary, localized structures were recently found for inclined porous medium convection with constant-temperature boundaries. We analyze traveling asymmetric, localized…
Fixed-flux Rayleigh-Bénard convection in doubly periodic domains: generation of large-scale shear
Chang Liu, Manjul Sharma, Keith Julien +1
This work studies two-dimensional fixed-flux Rayleigh-Bénard convection with periodic boundary conditions in both horizontal and vertical directions and analyzes its dynamics using…
Fluctuation-Induced Transitions in Anisotropic Two-Dimensional Turbulence
Lichuan Xu, Adrian van Kan, Chang Liu +1
Two-dimensional (2D) turbulence features an inverse energy cascade that produces large-scale flow structures such as large-scale vortices (LSVs) and unidirectional jets. We investi…
