Via a dissipativity-based analysis we show that optimal solutions exhibit the manifold turnpike phenomenon with respect to the manifold of thermodynamic equilibria. We illustrate our analytical findings via numerical results for a heat exchanger.en2405-8963IFAC-PapersOnLine2022305560IFACirreversible thermodynamic systemsmanifold turnpikeoptimal controlport-Hamiltonian systemsNatural Resources, Energy and EnvironmentEngineering and Applied OperationsOptimal control of thermodynamic port-Hamiltonian SystemsConference Paper10.1016/j.ifacol.2022.11.028Conference Paper
