Research on Thermal Conductivity of G-Type Three Period Minimally Curved Surface Structure
In response to the problem of large computational complexity in complex periodic cell structures,this article conducted a study on the thermal conductivity of G-type minimal curved surface structures and studied the calculation method of their equivalent thermal conductivity.Propose a calculation method for equivalent thermal conductivity.Based on the principle of measuring thermal conductivity using the steady-state method,the equivalent thermal conductivity of the G-type minimal surface structure was obtained through simulation analysis;By comparing the simulation analysis results of the G-shaped minimal surface with the equivalent model of the solid,the error between the two is within 1.5%.By fitting the formula,the calculation formula for the equivalent thermal conductivity of the G-type minimal surface structure is obtained.Compared with the simulation results,the error is within 2.5%.This formula can effectively characterize the equivalent thermal conductivity of the G-type minimal surface structure.
