Some example of tasks solved in Energy Conversion Department.

The frequency of the set of rotor and blades of the LP part of 200 MW steam turbine has been computed. Half of the rotor and the simplified set that involved ring with 53 blades of the last stage have been considered.

 

  

The geometry of the investigated model (left),
The second mode of the frequency of LP part of the rotor (right).

Stresses in the last stage due to rotation - 3000 rpm
