Board of CZ NC PWS for the period 2006 - 2009:

Brief history

The international cooperation in the research and standardization of thermophysical properties of water and steam originated practically in 1929. In this year the scientists and engineers engaged in power engineering from England, Germany, USA and Czechoslovakia met at the 1^st International Conference on Steam Tables in London, to remove the discrepancies in the steam data from the beginning of the 20^th century.

In Czechoslovakia, the research into thermophysical properties started in 1923 when the Masaryk´s Academy of Labor agreed upon the project dealing with the measurement of thermophysical properties of steam. The leading personalities were Professors J. Havliček, L. Miškovský, and later on their assistant J. Jůza.

After the 2nd World War, in 1956, the research into the properties of fluids was resumed in the Institute of Thermomechanics (IT CSAV) of the Czechoslovak Academy of Sciences. Under the leadership of Prof. Jůza started the systematic calculations in connection with the development of a wide-range equation of state based on experimental data, and later on also experimental works in high-pressure region within the frame of the State Plan of Research. With Prof. Jůza co-operated a small working team composed from workers of IT CASV and Technical University of Plzeň. By the end of 1990 the State Plan of Research was finished and substituted with the grant system. At that time it was contemplated to establish the National Committee on the Properties of Steam, to substitute the agreement from 1972 on which the cooperation with IAPWS was authorized by the collective membership of the Institute of Thermomechasnics by our Ministry of Foreign Affairs of that time. The Czech National Committee was established in 1994 under the auspices of the Academy of Sciences of the Czech Republic. It made possible to include other Czech Institutions and their workers into the cooperation with IAPWS.

Activities of the CZ NC PWS

• Organizes and carries out through its own members, in accord with the recommendations of IAPWS and needs of national economy, experimental research, critical evaluation of experimental data, and analytical description of properties of water, steam and aqueous solutions, is engaged in research of condensation and power plant chemistry, corrosion, fatigue and lifetime of materials under the influence of chemical admixtures in classical and nuclear power plants
• Informs Czech and on request the Slovak technical public about the activity of the IAPWS and about gained knowledge
• Introduces in the national practice internationally accepted computational documents of IAPWS, which are a binding international standards in power engineering and other industrial applications
• Publishes, within possibilities, the translations of important releases of IAPWS
• Carries out, in limited extend, consultation services.
