Heat and mass transfer in a channel with fins based on a triply periodic surface of the Schoen’s IWP type

The current study examines heat transfer in the channels of a heat exchanger with fins based on triply periodic minimal surfaces (TPMS) of the Schoen’s IWP type. A coupled heat and mass transfer problem is solved using numerical methods implemented in the software package Ansys 2019 R3, specifically in the Fluid Flow (Fluent) module. The results are compared with fins based on the Primitive surface. Dependencies are identified between pressure drop, the outlet temperature of the heat carrier,and the flow rate and geometric characteristics of the fins. The findings demonstrate a 18 % increase in heat transfer efficiency when using the Schoen’s IWP TPMS design in the heat exchanger compared to the Primitive-based fins.
