1. Three-Dimensional Computation of Eddy Currents in End regions of Synchronous Generators
Sammanfattning : .... LÄS MER
2. Adaptive Finite Element Methods for Div-Curl Problems
Sammanfattning : In this thesis, we develop and apply finite element methods to problems of div-curl type, mainly from applications in electromagnetics. In particular, we focus on least-squares formulations for problems with singularities, edge elements in eddy current computations, and the implementation of the finite element method. LÄS MER
3. Three-dimensional Finite Element Computation of Eddy Currents in Synchronous Machines
Sammanfattning : The thesis deals with the computation of eddy-current losses in the end regions of synchronous machines. Various magnetic and electric vector potential formulations of three-dimensional eddy-current problems are investigated. The equations are discretized by the finite element method with nodal or edge finite elements. LÄS MER
