초록

The triply periodic minimum surface (TPMS) shape with a complex geometry can easily manufactured from additive manufacturing processes. The TPMS shape has a high surface-to-volume ratio. In addition, the TPMS shape increases the possibility of the self-circulation when the fluid flows inside the TPMS structure. Due to these reason, the performance of the fluid flow filter can be greatly improved when the TPMS structure is applied to the filter. The aim of this paper is to investigate the influence of the design of the unit cell for TPMS on self-circulation characteristics of air using computational fluid dynamics (CFD). From the results of the CFD, the effects of the shape and the dimension of the unit cell for TPMS on the self-circulation pattern and the pressure difference are examined. Finally, a proper design of the TPMS is discussed from the viewpoint of self-circulation of air.
