A system of nonlinear difference equations and some sophisticated SOR schemes with variable relaxation factors for simulating the 3D-steady temperature distribution in a hydrogen inner-cooled turbogenerator rotor are derived. The numerical simulations show that the heat transfer between slots is nearly insulated.
