Abstract
The design of high-performing fluid and thermal devices is crucial for many aerospace
applications such as heat exchangers and flow manifolds. These systems often operate
under transient conditions, adding another layer of complexity to their design. Conventional
design principles have limitations as they depend on engineers to propose the
principal structure. In this dissertation, topology optimization (TO) is investigated as a method to design transient flow and thermal devices. To date, the use of TO for transient flow or thermal problems remains limited to experts in the field. Performing successful optimization heavily relies on the tuning of model and optimization parameters. By systematically investigating and improving the algorithms, their parameters and their characteristics, this thesis provides engineers with guidelines for their use.
