TITLE : FLOW THROUGH A REACTION TURBINE (LIBRARY CASE B525)

BY : CHAM Consultancy Team

DETAILS :

• This case represents the flow between two turbine blades in a cascade. The blade profile information was supplied in an arbitrary coordinate system and the Q1 transforms this into two surfaces set at the appropriate pitch and stagger angle.

• The non-orthogonal sheared grid has a portion upstream of the blades inclined at the gas inlet angle and a downstream portion inclined at the estimated outlet angle. Cyclic boundary conditions are used in these regions.

Pictures are as follows:

1. Velocity vectors
2. Pressure contours
3. Streamlines
