Pattern dynamics near homoclinic bifurcation in Rayleigh-Bénard convection
Pinaki Pal, Krishna Kumar, Priyanka Maity +1
We report for the first time the pattern dynamics in the vicinity of an inverse homoclinic bifurcation in an extended dissipative system. We observe, in direct numerical simulation…
Role of uniform horizontal magnetic field on convective flow
Pinaki Pal, Krishna Kumar
The effect of uniform magnetic field applied along a fixed horizontal direction in Rayleigh-Bénard convection in low-Prandtl-number fluids has been studied using a low dimensional…
Wavy stripes and squares in zero P number convection
Pinaki Pal, Krishna Kumar
A simple model to explain numerically observed behaviour of chaotically varying stripes and square patterns in zero Prandtl number convection in Boussinesq fluid is presented. The…
A model for interacting instabilities and texture dynamics of patterns
Alaka Das, Krishna Kumar, Narayanasamy Ganesh
A simple model to study interacting instabilities and textures of resulting patterns for thermal convection is presented. The model consisting of twelve-mode dynamical system deriv…
Asymmetric Squares as Standing Waves in Rayleigh-Benard Convection
Alaka Das, Ujjal Ghosal, Krishna Kumar
Possibility of asymmetric square convection is investigated numerically using a few mode Lorenz-like model for thermal convection in Boussinesq fluids confined between two stress f…
