Abstract: In this paper, a numerical study of hydrodynamics and heat transfer in a finned channel is carried out based on the topology of a thrice periodic minimal surface of the Primitive type with a varying angle of attack of the incoming flow. The fin is an elementary cell inscribed in a cube with an edge of 10 mm and an edge thickness of 1 mm. A numerical model of heat transfer has been developed using the ANSYS software package of the Fluent module. The dependences of power and hydraulic resistance on the angle of attack are presented. The distribution of the velocity and thermal fields of the flow during passage through the fins with the rotation of the structural elements in the channel by 0 ° and 45 ° is determined. The results of this study show that the angle of attack has a significant effect on the hydraulic (up to 8%) and heat exchange (up to 9%) properties of the model.

Key words: angle of attack, TPMS, finning, pressure loss, energy efficiency.
