This paper investigates the exponential stabilily of a model of a heat exchanger of counterflow type, whose boundary conditions are governed by boundary feedbacks. A theorem by F.L. Huang is applied to prove that the system satisfies the spectrum-determined growth assumption.
Keywords: Spectrum-determined growth assumption; exponential stability.
