1. Experimental studies in jet flows and zero pressure-gradient turbulent boundary layers
Sammanfattning : This thesis deals with the description and development of two classical turbulent shear flows, namely free jet and flat plate turbulent boundary layer flows. In both cases new experimental data has been obtained and in the latter case comparisons are also made with data obtained from data bases, both of experimental and numerical origin. LÄS MER
2. Forward Jet Production in ep-collisions at HERA
Sammanfattning : The production of forward jets has been measured in deep inelastic $ep$ collisions at HERA. The results are presented in terms of single differential cross sections as a function of the Bjorken scaling variable ($x_{Bj}$) and as triple differential cross sections $d^3 sigma / dx_{Bj}dQ^2dp_{t,jet}^2$, where $Q^2$ is the four momentum transfer squared and $p_{t,jet}^2$ is the squared transverse momentum of the forward jet.

3. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction
Sammanfattning : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. LÄS MER
4. Large Eddy Simulation for the Analysis of Supersonic Jet Noise Suppression Devices
Sammanfattning : Stricter noise regulations for commercial and military aircraft have increased interest in noise reduction techniques within the aerospace industry. To meet the requirements, new noise suppression technologies have to be developed and numerical methods need to be validated and possibly improved for the correct assessment of these technologies.

5. Jet-Ejecta Interactions in Neutron Star Mergers : How jets interacting with the surroundings affect multi-wavelength observations
Sammanfattning : In August 2017 a gravitational wave signal from a binary neutron star merger was detected for the first time, and it was followed by several electromagnetic detections that spanned the whole electromagnetic spectrum. Those observations proved the ejection of two dynamical components: mildly-relativistic neutron rich ejecta and an ultra-relativistic jet. LÄS MER
