Bistability and chaos in Taylor-Green dynamo
Rakesh Yadav, Mahendra K. Verma, Pankaj Wahi
Using direct numerical simulations we study dynamo action under the Taylor-Green forcing with Prandtl number less than one. We observe bistability with a weak magnetic field branch…
Period doubling route to chaos in Taylor-Green dynamo
R. Yadav, M. Chandra, M. K. Verma +2
We perform spectral simulations of dynamo for magnetic Prandtl number of one with Taylor-Green forcing. We observe dynamo transition through a supercritical pitchfork bifurcation.…
Bifurcation and chaos in zero Prandtl number convection
Pinaki Pal, Pankaj Wahi, Mahendra K. Verma +2
We present the detailed bifurcation structure and associated flow patterns near the onset of zero Prandtl number Rayleigh Bénard convection. We employ both direct numerical simulat…
