Although a meanline code solves simple algebraic equations, some difficulties arise in flows near choked condition. Using simplified 0-dimensional (0D) models, it is shown which flow variable drives this phenomena (total or meridional Mach number) depending on the boundary conditions. It is commented as well how the choked condition is modified depending on the loss coefficient used. Then, a novel numerical method based on a bisection approach is proposed to solve meanline equations. A simple method to enlarge speed lines obtained by the mean-line solver is also described. Finally, the performance map of a single-stage axial compressor is computed and compared with experimental data to show the capabilities of the proposed approach.
