Meridional flow modeling of turbomachinery. comparison with tests in two machines

摘要

We present in this paper a procedure allowing the calculation of the meridional flow in turbomachinery handling incompressible fluids. Starting with the three-dimensional flow, we will present the procedure allowing to separate the flow into two two-dimensional flows: the 2D blade-to-blade flow and the meridional flow supposed stationary and axisymmetric, where the blades are replaced by a force field. We will present next, the relationship between the blades' geometry and the calculation of the three components of these forces.
