TITLE : FLOW THROUGH A REACTION TURBINE (LIBRARY CASE B525)
BY : CHAM Consultancy Team
- 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
