Rotating Convection at Extreme Parameters on a Logarithmic Fourier Lattice

Watch a technical lecture exploring innovative numerical methods for studying rotating convection systems through the implementation of logarithmic Fourier lattices (LFL). Discover how this computational approach enables faster calculations compared to direct numerical simulations (DNS) when examining Rotating Rayleigh-Benard convection at high Rayleigh and low Ekman numbers. Learn about the advantages of combining LFL horizontal discretization with sparse Chebyshev methods in the vertical dimension, allowing for efficient simulation of extreme parameter ranges. Examine ongoing research in developing mixed LFL-Chebyshev solvers for both 2D and 3D applications, including comparative analysis with DNS results and discussions on potential extrapolation beyond current DNS capabilities. Presented by Keaton Burns from MIT at IPAM's Rotating Turbulence Workshop, this 48-minute presentation offers valuable insights into advanced computational methods for studying complex fluid dynamics systems.
