The global warming potential (GWP) of working fluids in thermodynamic cycles and their environmental impact have been gaining considerable attention within the recent years. The global objectives on climate protection are becoming increasingly ambitious, w ...
Energy geostructures (EGs) employ heat exchangers embedded in concrete geostructures, such as piles, walls, tunnels, and sewers. In this study, energy walls (EWs) are studied with an emphasis on the following objectives: (1) to understand the fundamentals ...
High-energy physics (HEP) experiments and space missions share a common challenge: thermal management in harsh environments. The severe constraints in both fields make cooling of electronic components a major design concern. This thesis aims to develop hig ...
This study explores and validates a machine learning approach for the practical, effective, and precise prediction of the thermo-physical characteristics that are essential for the analysis and design of shallow geothermal systems, including borehole heat ...

In this study, three manifold-microchannel heat exchangers were additively manufactured by direct metal laser sintering. The heat exchangers were manufactured from stainless steel (SS17-4) with an overall dimension of 64.2 x 46.0 x 27.1 mm. The thermal and ...
The employment of geostructures as structural supports and as heat exchangers represent an effective, renewable and sustainable way to satisfy thermal needs of the built environment. The structural support of conventional geotechnical structures is coupled ...
High-speed turbomachinery is commonly designed to achieve high power densities. Limited space for active cooling results in a challenging thermal management. A thermal modeling approach leveraging modern declarative programming capabilities is presented, y ...
