Dynamics of zero-Prandtl number convection near the onset
Pinaki Pal, Supriyo Paul, Pankaj Wahi +1
In this paper we present various convective states of zero-Prandtl number Rayleigh-Bénard convection using direct numerical simulations (DNS) and a 27-mode low-dimensional model co…
Chaotic dynamics in two-dimensional Rayleigh-Bénard convection
Supriyo Paul, Mahendra K. Verma, Pankaj Wahi +2
We investigate the origin of various convective patterns using bifurcation diagrams that are constructed using direct numerical simulations. We perform two-dimensional pseudospectr…
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.…
Dynamics of reorientations and reversals of large scale flow in Rayleigh-Benard convection
Pankaj Kumar Mishra, Arnab De, Mahendra K. Verma +1
We present a numerical study of the reversals and reorientations of the large scale circulation (LSC) of convective fluid in a cylindrical container of aspect ratio one. We take Pr…
