... and an absorbing media (like aerogel) as it influences thermal conductivity measurements made by the transient hot-wire method. They claim that the transient hot-wire technique is accurate for materials like aerogel if the extinction coefficient exceeds 5000 m −1 with temperatures near 25  ° C However, our hot...

... the film. The thermal conductivity measurements are sensitive to many other factors such as the thermal contact resistances, anisotropic material properties, surrounding air currents and temperature, and ambient humidity. A comprehensive numerical model was also developed to simulate the heat transfer...
