21. On model assisted probability of detection in eddy current evaluation
Sammanfattning : The goal of this work has been to investigate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current (EC) inspections. EC evaluation is one of the most applied methods for non-destructive evaluation (NDE) and is studied within this work. LÄS MER
22. Drop Break-up in High-Pressure Homogenisers
Sammanfattning : The overall aim of this project was to investigate the drop break-up process in milk homogenisers. This was done by measurements and calculations of the flow fields in the gap region and by visualisation of drops being broken up. To make visualisation and measurements possible, two scale models of a homogeniser gap were developed. LÄS MER
23. 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
24. On integral equation methods of solution to eddy current interaction problems
Sammanfattning : The eddy current method is used for nondestructive evaluation of conducting materials. To achieve a greater knowledge and insure safe and reliable evaluation methods, the use of mathematical models and simulations are needed. LÄS MER
