TEMPERATURE FIELD AND GRADIENTS IN ELEMENTS OF WELDED DISK TYPE TURBINE ROTOR UNDER STARTING CONDITIONS

Abstract

INVESTIGATIONS OF TEMPERATURE DISTRIBUTION IN A DISK TYPE WELDED ROTOR UNDER STARTING CONDITIONS WERE CARRIED OUT ON HYDROINTEGRATORS. The initial and boundary conditi ns of heat exchange, at which the investigations have been carried out, corresponded to turbine starting conditions. Characteristic in the construction of a disk type rotor is the sharp change in rotot profile at the zone where the disks are jointed with the cylinder, which ordinarily leads to irregularity in heating these elements. The temperature field was taken as the zone where the disk is jointed with the hollow cylinder, where considerable temperature gradients and stress concentrations do originate. (Author)
