Visit to thermodynamic Lab


Visit tothe Thermodynamic Institute of TU Bergakademie (Tuesday,  8th April 2014, 09.00-11.00)


Introduction: The Technische Universit├Ąt Bergakademie Freiberg (TUBAF) is a small GermanUniversity of Technologywith about 6000 students in the city of Freiberg, Saxony. It was established in 1765, by Prince Franz Xaver, regent of Saxony, based on plans by Friedrich Wilhelm von Oppel and Friedrich Anton von Heynitz, and is the oldest university of mining and metallurgy in the world.

Nowadays TU Bergakademie Freiberg is a Technical university with 6 faculties:

  • Mathematics,
  • Informatics / Chemistry, Biology and Physics /
  • Geoscience,
  • Geoengineering
  • Mining / Mechanical Engineering / Material Sciences / Business Administration and
  • Economics.

Virtuhcon(Virtual High Temperature Conversion Processes) is a research centre at TUBF. The centre was founded within the framework of the Entrepreunerial Regions Initiative "Centres of Innovation Competence: Create Excellence - Foster Talents" from the BMBF (Federal Ministry of Education and Research) and start working in 2009. The centre was initiated by eight departments of TU Bergakademie Freiberg:

  1. Institute for Energy Process Engineering and Chemical Engineering,
  2. Institute for Nonferrous Metallurgy and Purest Substances,
  3. Institute for Iron and Steel Technology,
  4. Institute for Materials Science,
  5. Instituteof HeatEngineering and Thermodynamics,
  6. Institute for Mechanics and Fluid Dynamics,
  7. Institute for Computer Sciences and
  8. Institute for Numerical Mathematics and Optimization.

Virtuhconfocuses on basic research in the field of partial oxidation processes in industry.

The visit wasimpressive and useful in several aspects:

  • Problems treated at the Institute
  • Methods that approach to study and work
  • Tools and equipment that the Institute use forthe measurement and detection.

It is particularly interesting to see and hear how they solve the different type of problems in the area of the propagation of heat, for different types of materials in many different ways performing detection and measurement of the thermal problems.

Approach to the phenomenonHeat propagationpresented by colleaguesfrom the Institutewas an easy waytoview thetheoreticalanddesign  approach to:

  • theintense exchangeof heat(forheat exchanger)
  • for preventingheatchanges(residential building)
  • to determine the time ofcoolingorheating,
  • to determine the optimalsize of the deviceandthe like.

The Institute hasan enviable scope of professional equipment, which is in a useful and high-quality manner used by fellow researchers for preparing their research papers and studies, as well as for students practice. Research occur in a wide range of thermodynamic parameters, so that we see the representation starting from vacuum conditions to the very high parameters of various thermodynamic conditions. The tests are carried out in different materials, and their different modifications. It was also interesting to follow the approach to the problem - defining links between the time and spatial change of the temperature atany point of the body, through which heat is conducted by, for example, as well as the possibility to measure thermal conductivity at temperatures above 16500 C.

Impressivewas part of an insulating material, and research done in this field, for example, the works related to the mutual comparison of thermal conductivity of insulation for buildings measured mass and performed a variety of methods, measurement capabilities of different materials, performed at different temperature levels, etc.. Tests are carried out in almost-all materials that can be found in the case of objects, from ceramics to brass. We saw also many tools with which to perform measurements and tests, such as laser-flesh apparatus and listen to itsability.
