| Abstract: | The calculation program for the working fluid thermodynamic properties(including water-water steam and air-wet gas) in CRGT was built with the hybrid programming method of MATLAB and VC.Ideal gas mixing model was adopt to simulate air and dry-gas property,IAPWS-IF97 standard model was adopt to calculate water and steam property.The property of wet-gas was calculated by advanced engineering method on the basis of the above models.The result shows that this method has an extremely high calculation speed and a... |
