Question 16.7: The preliminary design of an axial flow compressor is to be ...
The preliminary design of an axial flow compressor is to be based upon a simplified consideration of the mean diameter conditions. Suppose that the characteristics of a repeating stage of such a design are as follows:
Stagnation temperature rise ( \Delta T_{s t} ) | 30 K |
Degree of reaction ( \Lambda ) | 0.6 |
Flow coefficienty ( V_{f} / U ) | 0.5 |
Blade speed ( U ) | 300 m/s |
Assuming constant axial velocity across the stage and equal absolute velocities at inlet and outlet, determine the blade angles of the rotor for a shock free flow. ( c_{p} for air = 1005 J/kg K).
