CSD in industrial applications

Some example of tasks solved in Energy Conversion Department.

The stresses concentration coeffictients for the rotors and valves of HP and MP parts of the 13K215 steam turbine

The computations have been done on the basis of temperature measurements obtained during start-up process of real steam turbine set. The results have allowed to obtain coefficients of stresses concentration. These coefficients could be useful to real start-up monitoring.
