ORTIGOZA CAPETILLO, G.M.. Ecuaciones de advección-difusión, telégrafo y onda advectiva como superposiciones de transporte, difusión y onda: un enfoque didáctico. Rev. mex. fís. E [online]. 2007, vol.53, n.1, pp.48-51. ISSN 1870-3542.

In this work we present exact solutions of the advection-diffusion and the telegraph equations. These equations are considered as combinations of the basic equations: wave, heat and transport equation. Thus, in a natural way, a third combination that we called advection-wave is introduced. Although this equation is not so popular like the other combinations, it is a simple example of didactical value that allow us to explain physical and mathematical relations for the superposition of transport and wave motion.
