| Abstract: | On the basis of an IFC formula and one dimensional search method realized are a computer aided calculation of steam thermodynamic properties and a computer aided search of steam enthalpy entropy diagram. Through the use of two phase flow theory and compressible fluid thermodynamic principles the problem of steam and cooling water mixed flow multi stage multi orifice throttling can be transformed into a problem of iterative root extraction of a nonlinear equation. The above makes it possible to perform a computer aided analysis of the thermodynamic properties of a pressure and temperature reduction device for a steam turbine bypass system. |
