   Sammanfattning : In Sweden, housing accounts for about 23% of all energy consumption. Sweden wants to reach net zero carbon emissions by 2045; as such, it is likely that energy-saving measures for housing will be needed. Many existing buildings have been in operation for 50 years or more and are therefore in need of modernisation. LÄS MER

   Sammanfattning : This thesis is concerned with two distinct topics related to the study of wall-bounded turbulence: the connection between instantaneous three-dimensional coherent structures and mean-flow properties, and the development and analysis of pre-determined control techniques for adverse-pressure-gradient boundary layers.We examined regions with intense velocity fluctuations in various flowcases.
