چکیده:

The aim of present research is the performance simulation of axial flow turbine on different operating conditions by using of one dimentional modeling method.In this method by receiving the flow inlet conditions and turbine geometry, velocity triangles at blade inlet and outlet are obtained and performance characteristics of the turbine are calculated. As respects the importance of modeling for performance prediction and optimization in initial desing level, in followingwork, that is based on one dimentional modeling method, after the presentation of solution algorithm by trial and error methodand introduction of different loss models for modeling, the obtained results of modeling were examined for NASA single stage turbine and compared with experimental results. Comparison of the results with experimental data shows great agreement. Also according to these results, Kacker andOkapuu’s developed model gave the closest results to the refrence data.
