Simplified Modeling and Simulation Method for Surface Temperature Fields of Complex Structure Camouflage Nets

The complex surface structure of camouflage net poses significant challenges for direct modeling simulation calculations. The surface patterns and holes of camouflage net substantially affect convective heat transfer across the surface. Additionally, the holes in the net influence radiative heat transfer to targets beneath it. This paper simplifies the camouflage net into a flat tarpaulin surface and equates its corresponding physical properties. By treating the camouflage net model as a translucent structure with appropriate transmittance settings, its transmission effect can be simulated. To validate the computational method's accuracy, a field test was conducted. Comparing the collected field data with simulation results confirms the feasibility of this simplification approach.
