Numerical solutions for fractional reaction-diffusion equations

Fractional diffusion equations are useful for applications where a cloud of particles spreads faster than the classical equation predicts. In a fractional diffusion equation, the second derivative in the spatial variable is replaced by a fractional derivative of order less than two. The resulting solutions spread faster than the classical solutions and may exhibit asymmetry, depending on the fr...

Adaptive Numerical Simulation of Reaction - Diffusion Systems

The aim of this work is to find efficient and reliable numerical solutions of two complex problems under consideration. In the first application problem, an improved continuum model has been derived to describe the temperature and concentration distributions in gas-solid-fluidized beds with spray injection. The model equations for the nozzle spray are also reformulated to achieve reliable numer...

Nonexistence of Global Solutions in Time for Reaction-Diffusion Systems with Inhomogeneous Terms in Cones

We consider initial-boundary value problems for the reaction-diffusion systems with inhomogeneous terms in cones. In this paper we show the nonexistence of global solutions of the problems in time. Keyword and Phrases: reaction-diffusion, global nonexistence, inhomogeneous term, cone. AMS subject classifications: 35K45, 35K57.

Existence of Global Solutions in Time for Reaction-Diffusion Systems with Inhomogeneous Terms in Cones

We consider nonnegative solutions of the initial-boundary value problems in cone domains for the reaction-diffusion systems with inhomogeneous terms dependent on space coordinates and times. In our previous paper the conditions for the nonexistence of global solutions in time were shown. In this paper we show the condition of existence of global solutions in time.

Numerical Methods for Stiff Reaction-diffusion Systems

In a previous study [21], a class of efficient semi-implicit schemes was developed for stiff reaction-diffusion systems. This method which treats linear diffusion terms exactly and nonlinear reaction terms implicitly has excellent stability properties, and its second-order version, with a name IIF2, is linearly unconditionally stable. In this paper, we present another linearly unconditionally s...
