EFFECT ON STRESS DISTRIBUTION BY HOT GROOVE SHAPE ON STEAM TURBINE ROTOR[J]. Thermal power generation, 1997, (6): 3-6. DOI: 10.19666/j.rlfd.1997.06.002.
the thermal stress distribution in hot groove of steam turbine rotor was analyzed by means of boundary element method. A comparing analysis of the hot groove thermal stress with its different shapes was made. This paper provides scientific basis for the optimal design of hot groove shapes.
