Mitigating weaknesses of density-based thermo-fluid topology optimization: Using meta-optimization of modeling parameters

Power electronic systems are reaching higher efficiencies as their technology advances, which often results in components of smaller size with higher power densities. Cooling these components becomes increasingly challenging as high power densities require cooling with large heat fluxes. Topology optimization (TO) of thermo-fluids can be used to...

Applicability and challenges of automated design approaches for thermo-fluid components

This thesis addresses the capabilities and challenges of automated design approaches, specifically for ap-plication in which a combination of heat transfer and flow is needed. The objective is to use automateddesign approaches from literature and to identify the bottlenecks.For this purpose, an industrial thermal-fluid airshower is designed,...

Topology optimization of coupled heat problems: An investigation of a combined thermo-mechanical and thermo-fluid topology optimization towards improving optical performance of a beam-steering mirror

In modern ASML machines optical components play an important role in the lithography process. EUV light is transported from the source to wafer by reflective optics. These mirrors are subjected to large thermal loading, as a large portion of the reflected light is absorbed in the mirror structure. The portion of the absorbed light is strongly...
