Induced compositional layering in a convecting fluid layer by an endothermic phase transition

Induced compositional layering in a convecting fluid layer by an endothermic phase transition

An endothermic phase change in the presence of chemical heterogeneitles can act as an efficient filter, such that heavy material is sequestered below the phase change and light material is trapped above the phase change. Due to the fact that the endothermlc phase change damps thermal convection, it can act as a "trap door" for chemical heterogeneitles Ascending flows which are chemically dense ...

Solitons and the commensurate-incommensurate transition in a convecting nematic fluid.

Phase transition induced by a magnetic field

The magnetic catalysis of discrete chiral symmetry breaking in the 2+1 dimensional Nambu-Jona-Lasinio model is analyzed. A particular attention is paid to a possible application of the effect in solid state physics. The fermion contribution to the thermal conductivity as a function of the dynamical mass (energy gap in the spectrum) is estimated and is shown to be suppressed when a non-zero orde...

Visualising Multi-Phase Lattice Gas Fluid Layering Simulations

Complex fluids that exhibit phenomena such as layering and separation of multiple phases are computationally expensive to model using conventional numerical integration of partial differential equations. Lattice gas approaches are significantly cheaper to simulate and can still reveal good insights into the essential behaviours. We describe simulations of multi-phase layering in a lattice gas b...

Phase transition of the dry friction between crystalline surfaces induced by normal load

A major source of energy dissipation and surface wear is the kinetic friction at the interfaces of sliding bodies. Traditionally, on a macroscopic scale, this undesirable effect is reduced with lubricating the surfaces by introducing oil into their interface. An interesting phenomenon, called superlubricity, has been reported on a nanometer scale where dry (without lubricant oil) fruition and w...
