Front propagation and pattern formation in anisotropic bistable media
The effects of diffusion anisotropy on pattern formation in bistable media are studied using a FitzHugh-Nagumo reaction-diffusion model. A relation between the normal velocity of a front and its curvature is derived and used to identify distinct spatiotemporal patterns induced by the diffusion anisotropy. In a wide parameter range anisotropy is found to have an ordering effect: initial patterns...
متن کاملAverage crack-front velocity during subcritical fracture propagation in a heterogeneous medium.
We study the average velocity of crack fronts during stable interfacial fracture experiments in a heterogeneous quasibrittle material under constant loading rates and during long relaxation tests. The transparency of the material (polymethylmethacrylate) allows continuous tracking of the front position and relation of its evolution to the energy release rate. Despite significant velocity fluctu...
متن کاملConstant Front Speed in Weakly Diffusive Non-Fickian Systems
In certain polymer penetrant systems the e ects of Fickian di usion are dominated by nonlinear viscoelastic behavior Consequently such systems often exhibit concentration fronts unlike those seen in classical Fickian systems These fronts not only are sharper than in standard systems but also propagate at constant speed The mathematical model presented is a moving boundary value problem where th...
متن کاملLocalized states in bistable pattern-forming systems.
We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously generated by the system itself. We show that the phenomenon is generic and requires only the coexistence of two spatially periodic states. At the onset of the spatial bifurc...
متن کاملHigher-order Differencing for Phase-front Propagation in Geothermal Systems
We are testing higher-order differencing total variation diminishing schemes implemented in the reservoir simulator TOUGH2 to reduce numerical dispersion of phase fronts in geothermal flow problems. The schemes are called total variation diminishing because they employ flux limiters to prevent spurious oscillations that sometimes occur with other higherorder differencing schemes near sharp fron...
