Abstract
Insights and additionnal clarifications concerning the energy diffusion model [4] are in concern herein. We showed in former times under steady state conditions, that the diffusion model is well suited for an uncorrelated plane wave dynamics [7], energy behaviour modelling. We will prove, in this short note, that the later is not enough when transient dynamics is in concern. We thus propose a new equation alternative to the diffusion equation.
