%A Lewandowski, Janusz %D 2011 %T PROBLEMS OF WATER VAPOUR OF THERMODYNAMIC PROPERTIES DESCRIPTION IN MATHEMATICAL MODELLING OF TURBINE DYNAMICS %K %X It has been presented some problems of thermodynamic properties of water vapour description, especially of method of thermodynamic derivatives calculation. Formulas needed for mathematical modelling of turbine dynamics have been shown. The method of thermodynamic derivatives determining and base of structure of procedures for derivatives computation, in the time of turbine model calculation, have been discussed. %U https://papers.itc.pw.edu.pl/index.php/JPT/article/view/57 %J Journal of Power Technologies %0 Journal Article %P 37-53%V 57 %@ 2083-4195
