DIMOU, KYPRIANOS (author)Nowadays, climate change and global warming phenomena are becoming more and more serious issues. In order to sustain the enormous worldwide energy demand, society consumes a high amount of fuel, resulting into the steep increase of the level of CO\textsubscript{2} in the environment. Therefore, the massive greenhouse gases emissions in the...master thesis 2022

Quattrucci, Giacomo (author)The optimization of heat transfer in turbulent upward pipe flows is a very common problem in engineering, due to the wide range of applications. However, this set-up is usually categorised as mixed convection flow, which means that gravity plays an important role. Sometimes, it might lead to heat transfer deterioration. This research will...master thesis 2022

de Geus, Julia (author)A CFD study is made to get more insight in the flow, temperature and heat distribution in a side heated cavity filled with coarse grained porous media. This was investigated for 105≤Ra≤107 and 0.01≤Ri≤100. The question is how the solid beads influence the heat transfer. It was found that the spheres dampen the flow, influence the local heat...master thesis 2018
