Multiple critical Froude numbers for the centrifugal effects on heat transport in rotating Rayleigh-B\'{e}nard convection
arXiv:2606.06116v1 Announce Type: new Abstract: The influence of centrifugal effects in rotating Rayleigh-Benard convection is investigated using direct numerical simulations. We find that the Nusselt number decreases beyond a critical Froude number, Fr_c*.
Scale-invariance and characteristic length scale for the large-scale vortices in geostrophic convective turbulence with friction
arXiv:2606.02940v1 Announce Type: new Abstract: In geostrophic convective turbulence, large-scale vortices (LSVs) emerge through upscale energy transfer and are commonly regulated by large-scale friction. Yet the role of friction in setting the LSV size remains poorly understood. Here we perform direct numerical simulations of rotating Rayleigh-Benard convection with a linear friction term $\alpha\mathbf{u}$. Contrary to the classical prediction $L_\alpha\sim\alpha^{-3/2}$ obtained from the...
Data-driven Progressive Discovery of Physical Laws
Announce Type: replace-cross Abstract: Symbolic regression is a powerful tool for knowledge discovery, enabling the extraction of interpretable mathematical expressions directly from data. However, conventional symbolic discovery typically follows an end-to-end, "one-step" process, which often generates lengthy and physically meaningless expressions when dealing with real physical systems, leading to poor model generalization. This limitation fundamentally stems from its deviation from the...
