Effective control of two-dimensional Rayleigh--Bénard convection: invariant multi-agent reinforcement learning is all you need
Colin Vignon, Jean Rabault, Joel Vasanth +3
Rayleigh-Bénard convection (RBC) is a recurrent phenomenon in several industrial and geoscience flows and a well-studied system from a fundamental fluid-mechanics viewpoint. Howeve…
Two-phase flow simulations at 0-4 degrees inclination in an eccentric annulus
C. Friedemann, M. Mortensen, J. Nossen
Multiphase flow simulations were run in an eccentric annulus. The dimensions of the annulus were 0.1 and 0.05 m for the outer and inner cylinders, respectively, and the mixture vel…
Ocellaris: a discontinuous Galerkin finite element solver for two-phase flows with high density differences
Tormod Landet, Mikael Mortensen
In free-surface flows, such as breaking ocean waves, the momentum field will have a discontinuity at the interface between the two immiscible fluids, air and water, but still be sm…
Slope limiting the velocity field in a discontinuous Galerkin divergence free two-phase flow solver
Tormod Landet, Kent-Andre Mardal, Mikael Mortensen
Solving the Navier-Stokes equations when the density field contains a large sharp discontinuity---such as a water/air free surface---is numerically challenging. Convective instabil…
