Abstract: This work reports a custom instrument that employs a modified Ångström's method to measure the thermal diffusivity of foil-like materials in which heat propagates in one dimension. This method does not require a semi-infinite ...

Abstract: This work reports a method to measure thermal diffusivity of thin disk samples at high temperatures (approximately 900–1150 K) using a modified Ångström's method. Conventionally, samples are heated indirectly from the ...

Abstract: The thermal conductivity of soil is an important parameter in many engineering problems involving heat transfer, such as in ground source heat pump systems and freeze-thaw prevention projects. In these projects, not only ...

Abstract: This paper focuses on nonlinear oscillation of a space tether system connected to the Moon’s surface, elongating along the Earth-Moon line at L1 and L2 sides respectively. The full nonlinear elongation dynamics of the space ...
