Nasim, “On the solution of reaction-diffusion equations with double diffusivity,” International Journal of Mathematics and Mathematical Sciences, vol. 10, no. 1, pp. 163-172, 1987. doi:10.1155/S0161171287000206http://hdl.handle.net/1880/108672https://doi.org/10.11575/PRISM/43954In this paper, solution of a pair of Coupled Partial Differential equations is derived. These equations arise in the solution of problems of flow of homogeneous liquids in fissured rocks and heat conduction involving two temperatures. These equations have been considered by Hill and Aifantis, but the technique we use appears to be simpler and more direct, and some new results are derived. Also, discussion about the propagation of initial discontinuities is given and illustrated with graphs of some special cases.Journal Article2018-09-27enCopyright © 1987 Hindawi Publishing Corporation.
