Bridging the Rossby number gap in rapidly rotating thermal convection
Adrian van Kan, Keith Julien, Benjamin Miquel +1
Geophysical and astrophysical fluid flows are typically driven by buoyancy and strongly constrained at large scales by planetary rotation. Rapidly rotating Rayleigh-Bénard convect…
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…
Two-dimensional turbulent condensates without bottom drag
Adrian van Kan, Alexandros Alexakis, Edgar Knobloch
The extent to which statistical equilibrium theory is applicable to driven dissipative dynamics remains an important open question in many systems. We use extensive direct numerica…
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…
Phase Transitions in Anisotropic Turbulence
Adrian van Kan
Turbulence is a widely observed state of fluid flows, characterized by complex, nonlinear interactions between motions across a broad spectrum of length and time scales. While turb…
