热波在超低热导率材料中的传递特性
Thermal Wave Transfer Characteristics in Ultra-low Thermal Conductivity Materials
摘要
Abstract
Considering a single ultra-low thermal conductivity insulation material,the transfer pro-cess of external heat flow noise in a single stage insulation material is modeled by using generalized ther-moelasticity theory and one-dimensional thermomass theory.Combined with the CV model of one-dimensional Fourier heat conduction theory,the damping oscillation model of temperature was proposed,and the quasi-steady transfer process of external heat flow in single-layer materials was modeled.The functional relationship of temperature noise response to external heat flow noise was constructed,and the corresponding characteristics of node temperature were obtained.Through sensitivity analysis,the key parameters and their influencing rules of temperature noise attenuation were clarified.关键词
