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…
On exactly incompressible DG FEM pressure splitting schemes for the Navier-Stokes equation
Tormod Landet, Mikael Mortensen
We compare three iterative pressure correction schemes for solving the Navier-Stokes equations with a focus on exactly divergence free solution with higher order discontinuous Gale…
More efficient time integration for Fourier pseudo-spectral DNS of incompressible turbulence
David I. Ketcheson, Mikael Mortensen, Matteo Parsani +1
Time integration of Fourier pseudo-spectral DNS is usually performed using the classical fourth-order accurate Runge--Kutta method, or other methods of second or third order, with…
Fast parallel multidimensional FFT using advanced MPI
Lisandro Dalcin, Mikael Mortensen, David E Keyes
We present a new method for performing global redistributions of multidimensional arrays essential to parallel fast Fourier (or similar) transforms. Traditional methods use standar…
