Transient, Three-Dimensional, Finite-Element Analysis of Heat Flow in Turbine-Generator Rotors

The problem of three-dimensional, transient heat flow in the rotors of large turbine-generators is solved using a finite element formulation and employing new arch-shaped elements. Applications to negative sequence current heating and to rotor mechanical unbalance caused by thermal asymmetries are d...
