Topology optimization of transient fluidic and thermal devices

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.
