【摘要】：在变换热力学的基础上,通过坐标变换的方法,推导出三维任意形状热斗篷导热系数的通解表达式,并进行了全波仿真验证.结果表明:热流均能绕过保护区域流出,保护区域的温度保持不变,而且热斗篷外的温度场并没有破坏,具有很好的热保护和热隐身的效果.这一方法把变换热力学从二维拓展到三维,具有普遍的适用性.同时,这种技术为热流流动路径和目标温度场的控制奠定了理论基础,在微芯片、电动机的保护以及目标热隐身上有潜在应用.
[Abstract]:On the basis of the transformation thermodynamics, the general solution expression of the thermal conductivity of the three-dimensional heat cloak with arbitrary shape is derived by the coordinate transformation method, and the full wave simulation is carried out. The results show that the heat flux can bypass the protection zone and the temperature of the protection zone remains unchanged, and the temperature field outside the thermal cloak is not destroyed, so it has good thermal protection and thermal stealth effect. This method extends the transformation thermodynamics from two-dimensional to three-dimensional, and has universal applicability. At the same time, this technology lays a theoretical foundation for the control of heat flow path and target temperature field, and has potential applications in microchip, motor protection and target thermal stealth.
