Abstract

Recent advances in additive manufacturing technology have enabled rapid and inexpensive prototyping of designs to explore shape effects across a range of engineering applications. In this work, we measure the heat transfer performance of a range of heat exchangers based on triply periodic minimal surfaces (TPMS). The results showed that the sheet gyroid TPMS design produced a high rate of heat transfer and moderate pressure drop. The sheet gyroid TPMS design was further investigated to determine its performance over porosities ranging from 40% to 85%, hydraulic diameters from 2 to 10 mm, and wall thicknesses from 0.4 to 2.6 mm. Our results show that all correctly parameterised TPMS of the same type have…
