基于微流控自适应红外伪装薄膜研究
Research on Microfluidic-based Adaptive Infrared Camouflage Thin Film
摘要
Abstract
To address the insufficient adaptability of traditional infrared camouflage technologies in dynamic complex environments and multispectral detection,a microfluidic-based infrared camouflage film system is proposed for the adaptive matching of target and background infrared signatures through real-time thermal radiation regulation.A thermal-fluid-structure coupling simulation model comprising a solid substrate and embedded microchannels is established to analyze steady-state heat transfer characteristics.Simulations are performed with inlet flow velocities ranging from 0.25 to 5.00 m/s and channel spacings from 1 to 4 mm to determine the effects of flow velocity and structural parameters on temperature distribution.The surface temperature variations are verified through infrared imaging tests under various flow velocities and time sequences.The results indicate that higher flow velocities(e.g.,5.00 m/s)and smaller channel spacings(e.g.,1 mm)significantly improve temperature uniformity,with the maximum temperature difference reduced from 15℃to 2℃,thereby blurring the target's infrared contour.At flow velocities exceeding 0.50 m/s,the film surface temperature converges rapidly with the background,achieving effective infrared concealment.关键词
