【摘要】 本文在频域有限差分(FDFD)方法基础上,结合维纳混沌展开(WCE)和傅里叶变换的思想,简化控制方程,减少了计算量。计算了金薄膜与金薄膜、SiC薄膜与金纳米线阵列间的近场辐射换热,表明简化后的控制方程截断误差在可接受范围之内,SiC薄膜与金纳米线阵列间表面波的激发大大增强了辐射换热.更多还原

【Abstract】 This paper calculates the near-field thermal radiation heat transfer between two plane surface by directly solving Maxwell equation based on fluctuation-dissipation theorem.The random current source term is modified by Wiener Chaos Expansion and the controlling equations are reduced by Fourier transform.In this paper,we also compute the heat transfer between two gold films and between SiC film and gold nano-wire arrays.The calculation fits in with the analytical solutions well and the numerical error is in acceptable domain.The near-field thermal radiation between SiC film and gold nano-wire arrays is greatly enhanced.更多还原
