1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

3. 2. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Josep Plana Riu; [2022]
   Keywords : ;

   Abstract : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. READ MORE

4. 3. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
   Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

   Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

5. 4. Feasibility study on Thermal Anemometry at LWR conditions

   University essay from KTH/Fysik

   Author : Abishek Baskar; [2021]
   Keywords : Nuclear Enginnering; Thermal-Hydraulics; Instrumentation; Material technology; Fluid Dynamics. Light water reactors;

   Abstract : Dryout and Departure from Nucleate boiling (DNB) are utmost thermal-hydraulic concerns for the safety of LWRs. The behavior of two-phase flows at these conditions is still not fully understood. There is at least a need for a good local velocity and void fraction database at these conditions. READ MORE

6. 5. Interaction between cobalt nanoparticles and DPPC at pulmonary conditions

   University essay from KTH/Yt- och korrosionsvetenskap

   Author : Paula Sommer; [2021]
   Keywords : metallic nanoparticles; lipids; lung surfactants; adsorption; pulmonary fluid; metalliska nanopartiklar; lipider; lungtensider; adsorption; syntetisk lungvätska;

   Abstract : Nanomaterial produceras och används alltmer i tekniska lösningar för att förbättra t.ex. materialegenskaper. Eftersom ett materials egenskaper förändras när det är i nanoskala så påverkas även dess toxikologiska egenskaper. READ MORE
