Turbulent front speed in the Fisher equation: dependence on Damkohler number
A. Brandenburg, N. E. L. Haugen, N. Babkovskaia
Direct numerical simulations and mean-field theory are used to model reactive front propagation in a turbulent medium. In the mean-field approach, memory effects of turbulent diffu…
Alleviating alpha quenching by solar wind and meridional flow
Dhrubaditya Mitra, David Moss, Reza Tavakol +1
We study the ability of magnetic helicity expulsion to alleviate catastrophic -quenching in mean field dynamos in two--dimensional spherical wedge domains. Motivated by the phys…
A high-order public domain code for direct numerical simulations of turbulent combustion
N. Babkovskaia, N. E. L. Haugen, A. Brandenburg
A high-order scheme for direct numerical simulations of turbulent combustion is discussed. Its implementation in the massively parallel and publicly available Pencil Code is valida…
Turbulent transport in hydromagnetic flows
A. Brandenburg, P. Chatterjee, F. Del Sordo +3
The predictive power of mean-field theory is emphasized by comparing theory with simulations under controlled conditions. The recently developed test-field method is used to extrac…
Magnetic helicity fluxes in an alpha-squared dynamo embedded in a halo
A. Hubbard, A. Brandenburg
We present the results of simulations of forced turbulence in a slab where the mean kinetic helicity has a maximum near the mid-plane, generating gradients of magnetic helicity of…
Angular momentum transport in convectively unstable shear flows
Petri J. Käpylä, Axel Brandenburg, Maarit J. Korpi +2
Angular momentum transport owing to hydrodynamic turbulent convection is studied using local three dimensional numerical simulations employing the shearing box approximation. We de…
