Abstract

Improved volumetric (three dimensional) mathematical model of the cooling cylinder (compartment) turbines. It is implemented as a combination of continuous analytic and finite-difference solutions. At the same analytical expressions obtained with allowance for the thermal interaction of all bodies that make up the cylinder (rotor housings, clips, diaphragms, etc.) describe the heat balance in the radial direction, and finite difference - in the district and
