Description
An aerodynamic inverse shape design of turbomachinery blading in three-dimensional viscous flow is developed and implemented into a commercial CFD program, namely ANSYS-CFX. It is applied to redesign the rotor blades of an axial compressor stage and an axial turbine stage.
The design method is based on specifying one blade parameter, the stacking line (a blade line from hub to tip), and two other parameters such as the blade loading and thickness distribution or the pressure distributions on blade surfaces. This inverse design approach is fully consistent with the viscous flow assumption and is independent of the CFD approach taken.
An axial compressor stage E/CO-3 and turbine stage E/TU-3 are analysed and the results thus obtained are assessed against available experimental data. These stages are then inversely designed in order to improve their aerodynamic performance.
