چکیده
Streamline curvature is still a powerful method in predicting the performance of turbomachines whose results will be more realistic if a good estimation of losses and deviation is incorporated in the calculations. The present study improves the result of a single stage transonic compressor by incorporating shock and profile losses using previous correlations. Deviation is estimated on the basis of several correlations and results are then compared with the available experimental data. Looking at the effect of the above mentioned methods on outlet flow angle, meridian Mach number, pressure ratio and temperature, it is possible to recommend that one of the methods or a suitable combination of these methods be incorporated in the solution procedure.
