Convectons, anticonvectons and multiconvectons in binary fluid convection
Binary fluid mixtures with a negative separation ratio heated from below exhibit steady spatially localized states called convectons for supercritical Rayleigh numbers. Numerical continuation is used to compute such states in the presence of both Neumann boundary conditions and no-slip no-flux boundary conditions in the horizontal. In addition to the previously identified convectons, new states...
متن کاملDissipative Solitons in Binary Fluid Convection
A horizontal layer containing a miscible mixture of two fluids can produce dissipative solitons when heated from below. The physics of the system is described, and dissipative solitons are computed using numerical continuation for three distinct sets of experimentally realizable parameter values. The stability of the solutions is investigated using direct numerical integration in time and relat...
متن کاملTransition between curved and angular textures in binary fluid convection.
We report a transition from a curved texture to an angular texture in Rayleigh-B enard convection in a mixture of ethanol and water. The transition occurs as the Rayleigh number is reduced from a high value and approaches the traveling-wave branch and is observed at negative values of the separation ratio in uid mixtures, but not in a pure uid. We show that this transition may be understood in ...
متن کاملNumerical analysis of binary fluid convection in extended systems
Several aspects of the dynamics of convecting binary mixtures in large aspect ratio containers are analysed using high resolution numerical tools based on spectral methods. For two binary mixtures with separation ratio S = −0.127 and S = −0.021, we compute the Eckhaus stability boundaries of the spatially uniform travelling wave states arising in the primary subcritical bifurcation. The dynamic...
متن کاملRoll convection of binary fluid mixtures in porous media
We investigate theoretically the nonlinear state of ideal straight rolls in the Rayleigh– Bénard system of a fluid layer heated from below with a porous medium using a Galerkin method. Applying the Oberbeck–Boussinesq approximation, binary mixtures with positive separation ratio are studied and compared with one-component fluids. Our results for the structural properties of roll convection rese...
