Reijtenbagh, Jesse (author)Turbulent scalar mixing is prominent in all sorts of situations, being it in air pollution or making tea. However, this does not often lead to a homogeneously mixed fluid, but rather leads to regions of higher concentrations next to regions with significantly lower concentrations. This can be characterized by dividing the concentration field in...master thesis 2020

Ismail, U. (author)Report PRE-2628. The Algebraic Structure Based Model (ASBM) of Langer and Reynolds (2003) provides an innovative approach for modeling the turbulent stresses, while incorporating information on the structure of turbulence and providing closure for Reynolds-averaged Navier-Stokes equations. The normal turbulent stresses, for which the ASBM has...master thesis 2014

Gurunath, S. (author)In order to ramp up the conversion ratios and burn-up of nuclear reactors, it is inevitable to go to tightly packed fuel rods in the reactor. These nuclear reactors with tightly packed rod-bundles are characterized by interesting flow patterns, different from the ones encountered in regular channel and pipe flows. The correct prediction and...master thesis 2012

de Ruijter, R. (author)Downstream of man-made hydraulic structures, bed protections made of granular material are often used to prevent erosion of the bottom. The stones in the top layer of such granular filters must be able to withstand the hydraulic forces. Probably the best-known formula that is used to determine the stability of granular bed material is the design...master thesis 2004

Liek, G.A. (author)With the morphological models that are in use today, such as Delft2D-MOR, the scour that is calculated near the tip of hard coastal structures like breakwaters and groynes is often underestimated. This is most likely due to the fact that large horizontal turbulent eddies, which are formed when flow goes round these structures, locally enhance...master thesis 2000
