Thermal Coefficient Of Materials Measurement Unit.
Thermal Coefficient Of Materials Measurement Unit
A uni-directional heat flux is created through the test specimen, and measurements are made when the steady state is reached.
The parameters measured are those necessary for defining the heat transfer characteristics of a givmaterial :en
The measurement unit can be used to
determine the thermal coefficients of homogeneous or heterogeneous
materials and liquids, with one or two test boxes depending on the tests
to be carried out.
In the case of liquids or granular materials (powders or sand) the samples are placed in an hermetic box, with copper plates on the upper and lower surfaces.
Normal test temperatures are near ambient, but if required, materials can be tested at temperatures up to 80°C. The specimen dimensions are 270 x 270 mm, with thickness varying from 30 to 70 mm.
a) Laboratory experiments and students projects :
Using a twin-box system and depending on the types of boxes used.
b) Research :
The measurement unit comprises :
