Offer Description

Compact heat exchangers become more and more crucial to meet future demands for cost-effective and energy-efficient energy systems in a wide range of applications, including e.g. light-weight mobile systems, compressors and ventilation systems.The research group is presently looking for a motivated PhD researcher to work in the context of an interdisciplinary project that brings together research groups from KU Leuven and VITO to drastically improve the overall energy efficiency and material use for such compact heat exchangers, using emerging methods and methodologies in multiscale modeling, automated design and additive manufacturing (AM). In this project, the PhD student is responsible for the further development of the multiscale model, and the efficient shape optimization of the fin arrays in balanced compact heat exchangers, while accounting for constraints imposed by the AM process.  To do so, the PhD student will strongly collaborate within the TFE group and with KU Leuven’s renowned Additive Manufacturing research group and the other project partners.
While shape optimization based on computational fluid dynamics simulations has revolutionized the design of aerodynamic surfaces and channel surfaces over the last three decades, the development of these techniques for finned heat transfer devices is still an exciting and emerging research domain, in particular its inclusion in the overall heat exchanger design. Within this PhD project we investigate the practical use and limits of multiscale optimization of compact balanced heat exchangers. The research builds on the expertise in the TFE group on multiscale heat transfer modelling, simulation and optimization and on a state-of-the-art finite-element simulation and optimization software for large-scale flow and heat transfer simulations on the basis of the FEniCS software package, that paves the way to finally realize 3D optimal design of balanced compact heat exchangers.
