Filament bifurcations in a one-dimensional model of reacting excitable fluid flow

Global bifurcations and the appearance of a one-dimensional spiral wave in excitable media

It is well known that excitable media can sustain “fast” stable traveling pulses of excitation. In models for which analysis is tractable, the fast pulse solution is known to appear through a saddle-node bifurcation accompanied by a “slow” unstable traveling pulse. Furthermore, the uniform rest state is also a stable solution. It is generally assumed that the boundary between the basins of attr...

Three-dimensional chemically reacting radiative MHD flow of nanofluid over a bidirectional stretching surface

This study deals with the three-dimensional flow of a chemically reacting magnetohydrodynamic Sisko fluid over a bidirectional stretching surface filled with the ferrous nanoparticles in the presence of non-uniform heat source/sink, nonlinear thermal radiation, and suction/injection. After applying the self-suitable similarity transforms, the nonlinear ordinary differential equations are solved...

Effects of Thermal Diffusion and Radiation on Magnetohydrodynamic (MHD) Chemically Reacting Fluid Flow Past a Vertical Plate in a Slip Flow Regime

An analysis has been conceded to study the effects of Soret and thermal radiation effects on the magnetohydrodynamic convective flow of a viscous, incompressible, electrically conducting fluid with heat and mass transfer over a plate with time-dependent suction velocity in a slip flow regime in the presence of first-order chemical reaction. The slip conditions at the boundaries for the governin...

Numerical Scrutinization of Three Dimensional Casson-Carreau Nano Fluid Flow

This study presents the computational analysis of three dimensional Casson and Carreau nanofluid flow concerning the convective conditions. To do so, the flow equations are modified to nonlinear system of ODEs after using appropriate self-similarity functions. The solution for the modified system is evaluated by numerical techniques. The results show the impacts of involving variables on flow c...
