Diffusion-Free Dynamics in Rotating Spherical Shell Convection Driven By Internal Heating and Cooling
Neil T. Lewis, Tom Joshi-Hartley, Steven M. Tobias +2
The bulk properties of convection in stellar and giant planet interiors are often assumed to be independent of the molecular diffusivities, which are very small. By contrast, simul…

Data-driven discovery of the equations of turbulent convection
Christopher J. Wareing, Alasdair T. Roy, Matthew Golden +2
We compare the efficiency and ease-of-use of the Sparse Identification of Nonlinear Dynamics (SINDy) algorithm and Sparse Physics-Informed Discovery of Empirical Relations (SPIDER)…
