A Three Dimensional Scalar Potential Field Solution and its Application to the Turbine Generator End Region

A three dimensional scalar field solution is shown obtainable through a two dimensional grid given cylindrical symmetry. A valid field solution is obtained within current elements, the grid being excited by current injection at appropriate nodes as in the two dimensional vector potential grid. Test results verifying the method for predicting end region flux is presented. Because of its unique field solution within current masses, the method is applicable to problems such as forces on conductors in the end region of a turbine generator.
