Numerical Simulation of the Out-of-Plane Equivalent Thermal Conductivity of Honeycomb Core

Based on the actual working condition, the heat transfer model of honeycomb core in thickness direction was simplified. The out-of-plane equivalent thermal conductivity of aluminum honeycomb core was obtained by the methods of theoretical model and finite element numerical simulation. The present study indicates that the numerical simulation results are in good agreement with the calculation results of the simplified Swann-Pittman formula, which reveals that the numerical simulation method could accurately simulate the heat conduction of the honeycomb core.
