Rhombic Patterns Near a Bicritical Point in Periodically Forced Surface Waves
Krishna Kumar, Supriyo Paul, Dharmesh Jain
We present here a study of selection of rhombic patterns close to a bicritical point at the onset of primary surface instability in viscous fluids under two-frequency vertical vibr…
Proper orthogonal decomposition vs. Fourier analysis for extraction of large-scale structures of thermal convection
Supriyo Paul, Mahendra K. Verma
We performed a comparative study of extraction of large-scale flow structures in Rayleigh Bénard convection using proper orthogonal decomposition (POD) and {\em Fourier analysis}.…
Field correlations and the ultimate regime of turbulent convection
Mahendra K. Verma, Pankaj K. Mishra, Ambrish Pandey +1
Using direct numerical simulations of Rayleigh-Bénard convection (RBC) under free-slip boundary condition, we show that the normalized correlation function between the vertical vel…
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…
Bifurcations and chaos in large Prandtl-number Rayleigh-Bénard Convection
Supriyo Paul, Pankaj Wahi, Mahendra K. Verma
A low-dimensional model of large Prandtl-number () Rayleigh Bénard convection is constructed using some of the important modes of pseudospectral direct numerical simulations. A…
