6. Numerical investigation of curvature driven instabilities in toroidal plasmas
Sammanfattning : .... LÄS MER
7. Higher harmonic cavities at 3rd generation synchrotron light sources
Sammanfattning : Synchrotron radiation is a tool widely used in science. It is produced by electron accelerators called storage rings. With the high performance of the 3rd generation synchrotron light sources, the scientific results are excellent. It is important to identify and overcome the limitations of a storage ring in order to enhance its performance. LÄS MER
8. Flow instabilities in centrifugal compressors at low mass flow rate
Sammanfattning : A centrifugal compressor is a mechanical machine with purpose to convert kineticenergy from a rotating impeller wheel into the fluid medium by compressingit. One application involves supplying boost air pressure to downsized internalcombustion engines (ICE). LÄS MER
9. Transport Barriers in Plasmas and Fluids
Sammanfattning : In the present work different mechanisms for generation and suppression of turbulence are studied. The suppression of nonlinearly generated turbulence stabilized by temperature boundary conditions as well as turbulence generated by linear instabilities and suppressed by nonlinearly generated secondary flows are treated.

10. Inflation Mechanics of Hyperelastic Membranes
Sammanfattning : The applications of inflatable membrane structures are increasing rapidly in the various fields of engineering and science. The geometric, material, force and contact non-linearities complicate this subject further, which in turn increases the demand for computationally efficient methods and interpretations of counter-intuitive behaviors noted by the scientific community.
