1. Electromagnetic transformer modelling including the ferromagnetic core
Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
2. A lumped element transformer model including core losses and winding impedances
Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
3. Numerical analysis of coalescence-induced jumping droplets on superhydrophobic surfaces
Sammanfattning : Bio-inspired superhydrophobic surfaces are used in numerous technological applications due to their self-cleaning ability. One of the several mechanisms reported in literature and responsible for self-cleaning is the phenomenon of coalescence-induced jumping of droplets from such surfaces. LÄS MER
4. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials
Sammanfattning : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. LÄS MER
5. The dynamic behavior of the NiMH battery – Creating a versatile NiMH battery model
Sammanfattning : To facilitate the shift from fossil to renewable energy sources, energy storage is needed to cope with the intermittent nature of technologies such as solar, wind, and wave power. One storage alternative is battery-based stationary energy storage. LÄS MER
