This study investigates the aerodynamic performance of a large cylindrical 3D-printed Triply Periodic Minimal Surface (TPMS) Gyroid. A wind tunnel was used to introduce the Gyroid structure and explore its aerodynamic performance.

摘要

This study investigates the aerodynamic performance of a large cylindrical 3D-printed Triply Periodic Minimal Surface (TPMS) Gyroid. A wind tunnel was used to introduce the Gyroid structure and explore its aerodynamic performance. The obtained experimental results revealed good outcomes, indicative of the Gyroid’s favourable aerodynamic characteristics. We measured the local velocity within the gyroid’s structure and compared it with theoretical velocity. This helped us better understand how air moves through the structure. A range of Reynolds numbers that have been studied, specifically ranging from \(1.5\times {10}^4\) to \(1.4\times {10}^5\) . Additionally, an Ergun-type model is herein used to compare the pressure drop measurements, which further supported our observations. These findings are important and necessary for our further research on heat transfer phenomena across the Gyroid. This research is a part of a big project that is currently investigating the use of Gyroid lattice in civil engineering.
