Present modeling study of nanoenergetics focuses on the numerical simulation of reaction wave propagation in normal direction across nanoscale multilayers of aluminum and nickel combination. The governing equations for atomic and thermal diffusion are employed in one-dimensional semi-infinitely alternating Al/Ni multilayered structures and the numerical results show the established patterns of quasi-steady intermetallic reaction waves. Also, the reaction wave speed is confirmed to be highly independent of reaction wave directions in such nanoenergetic structures.
