1. Numerical modeling of auroral processes
Sammanfattning : One of the most conspicuous problems in space physics for the last decades has been to theoretically describe how the large parallel electric fields on auroral field lines can be generated. There is strong observational evidence of such electric fields, and stationary theory supports the need for electric fields accelerating electrons to the ionosphere where they generate auroras.

2. Experimental Investigations of Wave Motion and Electric Resistance in Collisionfree Plasmas
Sammanfattning : .... LÄS MER
3. A Simulation Approach to Plasma Waves
Sammanfattning : Electrostatic waves in the form of Broadband Electrostatic Noise (BEN) have been observed inthe Earth’s auroral region associated with high geomagnetic activity. Their broad frequencyspectrum consists of three electrostatic modes, namely electron plasma, electron acoustic andbeam-driven modes. LÄS MER
4. A Simulation Approach to High-Frequency Plasma Waves
Sammanfattning : Electrostatic waves in the form of Broadband Electrostatic Noise (BEN) have been observed in the Earth's auroral region associated with high geomagnetic activity. This broad frequency spectrum consists of three electrostatic modes, namely electron plasma, electron acoustic and beam-driven modes. LÄS MER
5. CFD modeling of biomass combustion and gasification in fluidized bed reactors
Sammanfattning : Biomass is an environmentally friendly renewable energy source and carbon-neutral fuel alternative. Direct combustion/gasification of biomass in the dense particle-fluid system is an important pathway to biomass energy utilization. LÄS MER
