11. Studies of water vapor transport and sorption in wood
Sammanfattning : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. LÄS MER
12. Analysis of carbon black oxidation
Sammanfattning : Diesel engines are known to be a major source of a highly pollutant material known as particulate matter, PM, which is a strongly threatening agent to human health. Therefore, diesel particulate filters are used to reduce PM emissions by trapping soot. LÄS MER
13. Transient Response of Grounding Systems Caused by Lightning: Modelling and Experiments
Sammanfattning : In order to achieve better lightning protection and electromagnetic compatibility (EMC) requirements, the needs for a proper grounding system and the knowledge of its transient behaviour become crucial. The present work is focused towards developing engineering models for transient analysis of grounding system with sufficient accuracy and simplicity for lightning studies. LÄS MER
14. Modelling the transient response of windings, laminated steel coresand electromagnetic power devices by means of lumped circuits : With special reference to windings with a coaxial insulation system
Sammanfattning : Electromagnetic transients impinging on electromagnetic power devices - such as electric machines, transformers and reactors - can stress the design severely. Thus the magnitudes of the transients are often decisive for the design of the devices. Further, the operation of a device can be transient in itself. LÄS MER
15. Analysis methodology for RBMK-1500 core safety and investigations on corium coolabiblty during a LWR sever accidnet
Sammanfattning : This thesis presents the work involving two broad aspectswithin the field of nuclear reactor analysis and safety. Theseare: - development of a fully independent reactor dynamics andsafety analysis methodology of the RBMK-1500 core transientaccidents and - experiments on the enhancement of coolabilityof a particulate bed or a melt pool due to heat removal throughthe control rod guide tubes.
