【摘要】：在變換熱力學的基礎上,通過坐標變換的方法,推導出三維任意形狀熱斗篷導熱系數(shù)的通解表達式,并進行了全波仿真驗證.結果表明:熱流均能繞過保護區(qū)域流出,保護區(qū)域的溫度保持不變,而且熱斗篷外的溫度場并沒有破壞,具有很好的熱保護和熱隱身的效果.這一方法把變換熱力學從二維拓展到三維,具有普遍的適用性.同時,這種技術為熱流流動路徑和目標溫度場的控制奠定了理論基礎,在微芯片、電動機的保護以及目標熱隱身上有潛在應用.
[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.
