Characterization of activities:
Department of Thermophysics is involved in development and application of the transient
techniques for measuring thermophysical properties of materials. Transient methods belong to
highly innovative dynamic measurement techniques that might give three parameters within a
single measurement, namely specific heat, thermal diffusivity and thermal conductivity. The
activities of the Department of Thermophysics was concentrated to the following:
Development of transient techniques, methodologies and measuring practices
considering specific requirements of industry. Activities were concentrated on
Pulse transient and Step-wise transient measuring technique. Methodology, and
optimal experimental set-ups were analyzed that give reliable data.
Development and construction of the instruments based on pulse transient method.
The prototypes of instruments RT 1.02 and RTB 1.01 were constructed and
prepared for production. While former instrument RT 1.02 is suitable for materials
having the temperature range 1 – 20 W m-1K-1, the latter one is aimed for materials
having thermal conductivity in the range 0.02 – 1 W m-1K-1. Portabkle and monitoring instruments
has been constructed for measurement of thermal conductivity in the range 0.04 up
to 1 W m-1K-1
Development of Standard protocols regarding transient measuring techniques
especially pulse transient and step-wise transient technique. This activity is
performed within a broad cooperation with various European laboratories to cover
the whole class of transient methods.
Development of thermophysical sensors for laboratory instruments as well as
for portable and monitoring instruments.
Application of the transient methods in various area of the technology where heat
transport is the control parameter.
