loss calculation in simulation of turbomachines
 
Dear all
Hi
I have a problem in the post-processing of turbomachinery problems. In fact, I don't know how to calculate flow loss coefficients: 1. secondary flow loss, 2. tip clearance loss and 3. annulus loss. There is an another important loss, profile loss, which can be determined by evaluation of total pressure difference after and before of each stage.
In 2D simulations, only determination of profile loss is possible; but I have no Idea how to determine other losses in 3D simulation.
