Scientist thermal and flow | Eindhoven/Hybrid

Within the TNO Semicon Equipment & Metrology (SEM) department, the Thermal Fluid Engineering (TFE) team is active in the field of micro flow and thermo dynamics and bulk chemical process interaction behaviour (e.g. with plasma). The largest part of the international and diverse SEM department is located in Delft, however the TFE team is located in Eindhoven. The TFE team actively participates in large research projects primarily in the fields of High Tech Equipment design for Immersion Lithography and High Performance Thermal Management (micro cooling). Other research contributions are made on the topics of sustainability for semicon, such as gas recycling and electrification of the chemical industry. The projects are funded by governmental entities or by companies and organisations such as ASML, Brightsite and NXP.

You will be working in projects that vary from developing a new concept or technology, to problem analysis of existing machines or setups. These projects require a combination of analytical capacity, physical understanding and collaboration with other experts in multidisciplinary teams. You will develop both numerical and analytical models and possibly develop and perform experiments on prototype setups. Tools often used for analysis are Matlab/Python and (commercially) available numerical packages such as: Comsol, Fluent, Ansys or OpenFoam. Typical topics are phase transition, micro-fluidics, two phase flow and plasma-process interaction.
