1. Computational Fluid Dynamics of the flow in a diffuser : - like geometry
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Simulations were performed to investigate flow separation of an asymmetricdiffuser - like geometry. The geometry used for the simulations was modeledafter an experimental setup with recorded flow data, which was compared tothe simulated data. For all simulations, steady state flow at the inlet was usedwith the assumption of a 2D flow. READ MORE

2. Rocket Jet Impinging on a Surface
University essay from KTH/Teknisk mekanikAbstract : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. READ MORE

3. Design of compact automotive heat exchanger, analysing the effects of RANS models and utilising Additive Manufacturing
University essay from KTH/FysikAbstract : The analytical modelling of complex turbulent airflow remains one of the great unsolved mysteries of physics, but in this paper two widely used Reynolds Averaged Navier-Stokes models (k-$\epsilon$ and k-$\omega$ SST) are compared while designing a heat exchanger for the KTH Formula Student electric race car. CAD software was used to design lattices for the heat exchanger core and theorise about how to increase heat transfer while also taking into account the utilisation of metal additive manufacturing.

4. Study of a vertical slot fish ladder : Evaluation of flow dynamics through a standardized bypass and the effect of predesigned roughness elements
University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskapAbstract : Migrating freshwater fish population has been significantly declined, mostly by the obstruction of their migratory routes by hydropower dams. To diminish such impacts, fish ladders have been developed to facilitate the passage of migrating fish. READ MORE

5. Interscale transport of Reynolds stresses in wall-bounded flows
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.
