Global Stability in the CSTR

Global StaMlity in the CSTR.— The failure of linear stability analysis to cover the macroscopic behaviour of the CSTR is well illustrated by the oscillatory states computed by Aris and Amundson for such a reactor operating with feedback control. Local stability analysis indicates an unstable equilibrium state but in the large this is surrounded by a stable limit cycle and the resultant behaviour is one of temperatures and concentrations oscillating about an unstable state, rather than approaching a stable one. [Pg.377]

A broader view of the reactor stability is essential and the problem of establishing the global behaviour of the reactor has been attacked from two different viewpoints. [Pg.377]
