A multi-objective optimal design method for thermal energy storage systems with PCM: A case study for outdoor swimming pool heating application
(Journal article; Peer reviewed, 2020)Traditional design methods for thermal energy storage systems (TES) with phase change material (PCM) are mostly based on worst-case scenario, which causes too large size of main components. Current optimal design methods ... -
A multi-objective optimisation framework to design membrane-based energy recovery ventilation for low carbon buildings
(Peer reviewed; Journal article, 2023)Membrane energy exchangers (MEEs) are increasingly being studied and utilized to contribute to realising energy-efficient building services and providing satisfactory indoor environments. The performance of MEEs has been ... -
A multi-objective optimization method for industrial park layout design: The trade-off between economy and safety
(Peer reviewed; Journal article, 2021)The general layout design significantly impacts the economy and safety performance of an industrial park. In most of the previous works, safety issues are converted to economic numbers in objective functions. However, this ... -
Multi-Row Adjoint-Based Optimization of NICFD Turbomachinery Using a CAD-Based Parametrization
(Journal article, 2021)Currently, most of the adjoint-based design systems documented in the open literature assume that the fluid behaves as an ideal gas, are restricted to the optimization of a single row of blades, or are not suited to impose ... -
