Abstract: In this work, a study of hydrodynamics in the walls of a Schwartz P triply periodic minimal surface was performed. TPMS lattices consisting of 1, 8, and 27 unit cells were chosen as the initial geometry for CFD modeling. The fluid flow problem was solved using the Fluent module of the ANSYS software package. In the course of solving the problem, the vector fields of the velocity distribution were obtained and the pressure losses in the TPMS channels were determined. Based on the analysis of the graph of the dependence of pressure losses on the flow velocity, an analytical dependence was obtained to determine the pressure losses for Schwarz P an elementary cubic cell with a cube edge length
and wall thickness
.
