Three-dimensional simulations of spiral waves in reacting and diffusing media on DSM computers

چکیده
Parallel ADI and CG methods based on the time-linearization of the three-dimensional , reaction-diffusion equations which govern the propagation of spiral waves in excitable media, have been implemented on both shared-and distributed-memory computers. ADI has been implemented by means of a dynamic block cartesian decomposition and its efficiency tends to that of the CG technique as the mesh is refined. The largest efficiency of CG was obtained on an Origin-2000 with a message passing model, private memory and 16 processors, and the efficiency of CG is larger than that of ADI.

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...
متن کاملGeneration of Love Wave in a Media with Temperature Dependent Properties Over a Heterogeneous Substratum
The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semi-infinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent. The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Lo...
متن کاملOn Interaction of T S Waves and 3 D Localized Disturbance in a Divergent Flow Under Zero Pressure Gradient
To simulate the effect of free st ream turbulence on turbulent spot formation, experiments were conducted on the interaction of localized three-dimensional disturbances with the harmonic waves in a laminar boundary layer on a flat plate. Experiments conducted in three-dimensional diverging flow (but zero pressure gradient) show, while individually the disturbances decay downstream, their intera...
متن کاملEffects of shear and bulk viscosity on head-on collision of localized waves in high density compact stars
Head on collision of localized waves in cold and dense hadronic matter with and without shear and bulk viscosities is investigated. Non-relativistic dynamics of propagating waves is studied using the hydrodynamics description of the system and suitable equation of state. It will be shown that the localized waves are described by solutions of the Burgers equation. Simulations show that the propa...
متن کاملThe effect of mechanical deformation on spiral turbulence
– The behavior of spiral turbulence in mechanically deformed excitable media is investigated. Numerical simulations show that when the forcing frequency is chosen around the characteristic frequency of the system, complicated spiral turbulence may be quenched within a shorter evolution time, compared to the case free of mechanical deformation. It is shown that the observed phenomenon occurs due...
