Effects of Anisotropy, Convection, and Relaxation on Nonlinear Reaction-Diffusion Systems

Computation
The effects of relaxation, convection, and anisotropy on a two-dimensional, two-equation system of nonlinearly coupled, second-order hyperbolic, advection–reaction–diffusion equations are studied numerically by means of a three-time-level linearized ...
