Computational techniques for metastable steam parameters determination in no equilibrium expanding flow in turbine channel
Two computational techniques to define metastable steam parameters are considered. First technique is based on decision of two-dimensional differential equations system for no equilibrium wet steam flow expansion. This technique allow to calculate stationary and no stationary flows of wet steam, to...

Journal of Mechanical Engineering| Summary: | Two computational techniques to define metastable steam parameters are considered. First technique is based on decision of two-dimensional differential equations system for no equilibrium wet steam flow expansion. This technique allow to calculate stationary and no stationary flows of wet steam, to define aerodynamic parameters, wetness and overcooling in each time for each point of calculating region. Second, simplified technique is based on calculating of thermodynamic properties of water and water steam, using International equations system IAPWS-IF97 and IAPWS-95. Compare of the test results, obtained with these two techniques, is shown |
