Measurement of Thermal Diffusivity Using Infrared Thermography

Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | This book highlights the thermal characterization of templated nanostructures using an infrared (IR) thermography based non-contact technique. One dimensional bismuth telluride Bi2Te3 nanostructures were grown using anodic alumina (AAO) template assisted electrodeposition technique. An infrared thermography based technique was then developed for the in-plane thermal diffusivity measurements of these templated nanocomposites. The thermal diffusivity of the nanowires alone was estimated through comparing the experimental results with the predictions made by a first order lower bound model (FOLBM). A mathematical background of the proposed technique with simulation studies is also reported. The distinct achievement of the present study is in-plane thermal diffusivity measurements of one dimensional templated nanostructures using infrared thermography, for the first time. The efficient and reliable technique developed and illustrated is well supported by theory, modelling and simulation. It has potential for very wide applicability.…
