A port-Hamiltonian formulation of coupled heat transfer [PDF]
Mathematical and Computer Modelling of Dynamical Systems, 2022 Heat transfer and cooling solutions play an important role in the design of gas turbine blades. However, the underlying mathematical coupling structures have not been thoroughly investigated. In this work, the port-Hamiltonian formalism is applied to the

Coupled heat transfer model for the combustion and steam characteristics of coal-fired boilers
Engineering Applications of Computational Fluid Mechanics, 2021 This paper presents a coupled heat transfer model for coal-fired boilers that integrates boiler’s fire side computational fluid dynamics (CFD) solution with the boiler’s steam cycle, and thus, can predict the boiler steam temperatures subject to ...

Discrete adjoint for coupled conjugate heat transfer
Structural and Multidisciplinary Optimization, 2023 AbstractThe typical method to solve multi-physics problems such as Conjugate Heat Transfer (CHT) is the partitioned approach which couples separate solvers through boundary conditions. Effective gradient-based optimisation of partitioned CHT problems requires the adjoint of the coupling to maintain the efficiency of the original multi-physics coupling,
