6. Robust optimisation of the pressure-gradient distribution in turbulent boundary layers
University essay from KTH/MekanikAbstract : In order to better characterise pressure-gradient turbulent boundary layers (TBLs), and to advance the theory of these flows, typically canonical conditions are required. This is achieved by keeping the Clauser pressure-gradient parameter, β, constant along the streamwise direction, see for instance Mellor and Gibson [9] and Bobke et al. READ MORE

7. Reactive-Di usive Flow Inside Porous Medium
University essay from KTH/MekanikAbstract : Understanding the reactive-di usive turbulent ow inside porous media is interesting in many applications. It could have geochemical applications such as describing the rock dissolution patterns in river beds or the e ect of riparian zones in nitrate attenuation. Other applications could be, e.g. READ MORE

8. Numerical studies on receptivity and control of a three-dimensional boundary layer
University essay from KTH/MekanikAbstract : Receptivity in three-dimensional boundary layer ow to localized roughness elements over a at plate is studied by means of direct numerical simulations (DNS). The surface roughness is modeled by applying nonhomogeneous boundary conditions along the wall as well as considering as a surface deformation by inserting the bump shape into the numerical mesh.
