  7. Abstract:
  8. With everyday increasing application of gas turbine in different industries, fast and accurate tools for design, analysis and performance estimation of gas turbines have found many proponent; Compressors, as one of the most important parts of gas turbines, are no exception to this ordinance. Although development of Computational Fluid Dynamics (CFD) method was a great aid to improve the accuracy of this tools, complexity and being time consume make them uncommon and unpopular during preliminary design and analysis process. So it could be imply that simple analysis methods, such as 1D, 2D and quasi-3D, are not only not abandoned, but also very practical and most applied in preliminary design, analysis and upgrading of turbomachinaries. This text presents the development of a 2D compressor analysis tool in meridional plane by streamline curvature method. This modeling uses inviscid fluid solution, by solving potential flow through the compressor on streamlines, based on combination of Katsanis and Aungier methods, and then entangle boundary layer and viscosity effects in solution, with help of experimental and empirical correlations, such as Hirsch and Wright-Miller models. So as to validating the developed tool, for start, a sample blade row, suggested by Katsanis, analyzed and compared to his presented results. After that for certifying this method with a real compressor, first row of NASA Rotor 37 was modeled and compare to its experimental performance data. In each analysis results are demonstrated as velocity and thermodynamic properties distribution over the solution field
