1. The impact of turbulence on supernovae shockwaves
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The momentum and energy injection from supernovae is one of the main feedback modes, and is therefore key to the understanding of galaxy evolution and star formation. However, due to low resolution, large scale galaxy simulations often have issues with accurately modelling supernovae, and therefore rely on sub-grid models. READ MORE

2. Potentials and limitations of 1D, 2D and coupled 1D-2D flood modelling in HEC-RAS
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : Hydraulic models can be used to predict the consequences of flooding events. In this project, three hydraulic models were constructed using the software HEC-RAS, and compared through a case study on Höje river catchment. READ MORE

3. Cloud Overlap Assumption and Cloud Cover Validation for HARMONIE-AROME
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : One major challenge in representing the state of the atmosphere through weather forecast models, is the parametrization of sub-grid clouds. At every vertical column of grid cells within a weather forecast model, the fractional cloud cover is assumed to overlap according to a prescribed Cloud Overlap Assumption (COA). READ MORE

4. Characterization of gas transport inside a package
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : A study of a sterilizing flow in a package is done. The study is done with the commercial code Fluent using Large Eddy Simulation and validated with both Laser Induced Fluorescence and Particle Image Velociometry. The velocity field is examined in several ways; with changes in grid size, inlet conditions and sub-grid scale models. READ MORE
