An efficient order−N real-space Kubo approach is developed for the calculation of the thermal conductivity of complex disordered materials. The method, which is based on the Chebyshev polyno-mi...
Using a full dispersion description of phonons, the thermal conductivities of bulk Si and Bi2Te3 are evaluated using a Landauer approach and related to the conventional approach based on the Boltzmann...
Thermal conductivity is one of the key parameters in the figure of merit of thermoelectric materials. Over the past decade, most progress in thermoelectric materials has been made by reducing their th...
The parameters used to describe the electrical conductivity of a porous material can be used to describe also its thermal conductivity. A new relationship is developed to connect the thermal conductiv...
Purpose: In this study we report measurements of effective thermal conductivity by using 3ω method and effective viscosity by vibro-viscometer for SiO2-water and Al2O3-water nanofluids at different p...
微热探针法测试热导率系统已被广泛应用于食品材料热导率的测试中。但是,由于实验条件或实验设备的限制,基于理想的线热源瞬态模型测量原理得到的结果会产生某些测试误差。针对测试误差,从探针输入电压、加热时间和样品的径向尺寸等装置操作参数的选择着手,通过实验,得到装置系统测定中输入电压的最佳值为2.5~6.5V、加热时间最佳值为20~50s。最后通过实际测试,得到了番茄果实在不同成熟阶段的热导率变化规律。
Thermal Barrier Coatings (TBCs) were first successfully tested in the turbine section of a research gas turbine engine in the mid-1970s. By the early 1980s they had entered revenue service on the vane...
For a thorough understanding of the behaviour of foundry mould mixtures, a good knowledge of thermal properties of mould materials is needed. Laboratory determination of thermal conductivity of mould...
