| Resumen |
This article presents a local stability study for an endoreversible Chemical Reactor (ECR). The model consists of two particle reservoirs, one at high chemical potential µ1 and the other at low chemical potential µ2 (the terms “high” and “low” refer to the situation in which µ1 > µ2 ). There are two particle resistors (in this work for simplicity we take h1 = h2 = h), that restrict the particle flows N1 and N2 . The net result is a particle flow drop from N1 to an intermediate particle reservoir N3 and from N4 to N2. From the local stability analysis it was concluded that the ECR is stable for every value of h, C1 and τ = nx/ny. After a small perturbation, the system declines to the steady state with two different relaxation times both being proportional to C, h and τ. Finally, when the power output in the steady state versus τ is plotted, it demonstrates how an increment of τ can improve the system stability. This suggests a compromise between the stability and the engine energetic properties driven by τ |
