Sea ice motion as a stochastic process
Srikanth Toppaladoddi
We use tools from statistical physics to develop a stochastic theory for the drift of a single Arctic sea-ice floe. Floe-floe interactions are modelled using a Coulomb friction ter…
Seasonal evolution of the Arctic sea ice thickness distribution
Srikanth Toppaladoddi, Woosok Moon, John S. Wettlaufer
The Thorndike et al., (\emph{J. Geophys. Res.} {\bf 80} 4501, 1975) theory of the ice thickness distribution, , treats the dynamic and thermodynamic aggregate properties of t…
A stochastic model for the turbulent ocean heat flux under Arctic sea ice
Srikanth Toppaladoddi, Andrew J. Wells
The physics of planetary climate features a variety of complex systems that are challenging to model as they feature turbulent flows. A key example is the heat flux from the upper…
The combined effects of buoyancy, rotation, and shear on phase boundary evolution
S. Ravichandran, S. Toppaladoddi, J. S. Wettlaufer
We use well-resolved numerical simulations to study the combined effects of buoyancy, pressure-driven shear and rotation on the melt rate and morphology of a layer of pure solid ov…
The role of grain-environment heterogeneity in normal grain growth: a stochastic approach
Thomas Breithaupt, Lars N. Hansen, Srikanth Toppaladoddi +1
The size distribution of grains is a fundamental characteristic of polycrystalline solids. In the absence of deformation, the grain-size distribution is controlled by normal grain…
Nonlinear interactions between an unstably stratified shear flow and a phase boundary
S. Toppaladoddi
Well-resolved numerical simulations are used to study Rayleigh-Bénard-Poiseuille flow over an evolving phase boundary for moderate values of Péclet () an…
Thermal Convection over Fractal Surfaces
Srikanth Toppaladoddi, Andrew J. Wells, Charles R. Doering +1
We use well resolved numerical simulations with the Lattice Boltzmann Method to study Rayleigh-Bénard convection in cells with a fractal boundary in two dimensions for and…
The combined effects of shear and buoyancy on phase boundary stability
Srikanth Toppaladoddi, John S. Wettlaufer
We study the effects of externally imposed shear and buoyancy driven flows on the stability of a solid-liquid interface. By reanalyzing the data of Gilpin \emph{et al.} [\emph{J. F…
Penetrative Convection at High Rayleigh Numbers
Srikanth Toppaladoddi, J. S. Wettlaufer
We study penetrative convection of a fluid confined between two horizontal plates, the temperatures of which are such that a temperature of maximum density lies between them. The r…
Roughness as a Route to the Ultimate Regime of Thermal Convection
Srikanth Toppaladoddi, Sauro Succi, John S. Wettlaufer
We use highly resolved numerical simulations to study turbulent Rayleigh-Bénard convection in a cell with sinusoidally rough upper and lower surfaces in two dimensions for …
Statistical Mechanics and the Climatology of the Arctic Sea Ice Thickness Distribution
Srikanth Toppaladoddi, John S. Wettlaufer
We study the seasonal changes in the thickness distribution of Arctic sea ice, , under climate forcing. Our analytical and numerical approach is based on a Fokker-Planck equa…
Theory of the sea ice thickness distribution
Srikanth Toppaladoddi, J. S. Wettlaufer
We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution due to Thorndike et al., (1975) into a Fokker-Pl…
Tailoring boundary geometry to optimize heat transport in turbulent convection
Srikanth Toppaladoddi, Sauro Succi, John S. Wettlaufer
By tailoring the geometry of the upper boundary in turbulent Rayleigh-Bénard convection we manipulate the boundary layer -- interior flow interaction, and examine the heat transpor…
Vortex shedding patterns, their competition, and chaos in flow past inline oscillating rectangular cylinders
Srikanth Toppaladoddi, Harish N Dixit, Rao Tatavarti +1
The flow past inline oscillating rectangular cylinders is studied numerically at a Reynolds number representative of two-dimensional flow. A symmetric mode, known as S-II, consisti…
