Numerical Simulations of Internal Wave Generation by Convection in Water
Daniel Lecoanet, Michael Le Bars, Keaton J. Burns +4
Water's density maximum at 4C makes it well suited to study internal gravity wave excitation by convection: an increasing temperature profile is unstable to convection below 4C, bu…
Conduction in low Mach number flows: Part I Linear & weakly nonlinear regimes
Daniel Lecoanet, Benjamin P. Brown, Ellen G. Zweibel +3
Thermal conduction is an important energy transfer and damping mechanism in astrophysical flows. Fourier's law - the heat flux is proportional to the negative temperature gradient,…
Approaching the Asymptotic Regime of Rapidly Rotating Convection: Boundary Layers vs Interior Dynamics
S. Stellmach, M. Lischper, K. Julien +5
Rapidly rotating Rayleigh-Bénard convection is studied by combining results from direct numerical simulations (DNS), laboratory experiments and asymptotic modeling. The asymptotic…
