- Abstract:
- This work deals with the dynamic thermal conductivity (λ) measurements by hot wire method. This measurements are performed at unstationary state conditions (short time). Very thin (0.05 mm) manganin wire is supplied by DC electrical power and produces a thermal impulses which pass through the testing sample. Dynamics of this process depends on the type of the sample material. Temperature, electric power and time elapsed during the process are measured parameters from which thermal conductivity could be calculated. Measurement results are compared with those gained by the standard guarded hot plate (stationary) method. Testing samples are made from isotropic and homogenous materials.
