Stability analysis of reaction-diffusion equations with double diffusivity system

الملخص EN

Stability analysis for steady state solution of reaction-diffusion equations with double diffusivity discuss and arise in the solution of problems of flow of homogeneous liquids and heat conduction involving air-temperature u (x, t) and a grain-temperature V (x, t), the resulting of this analysis shows that the system is stable when : Dk4 + aJLk2 + b2Lk2 + b2a ; L2 – b ; a2L2 > 0.
