1. 1. Modelling Gas Flow Behaviour in Gas Atomizer

   University essay from KTH/Materialvetenskap

   Author : Aravind Senan Vasanthasenan Reji; [2022]
   Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

3. 2. An input-sample method for zonotopic obstacle avoidance with discrete-time control barrier functions

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Xiong Xiong; [2022]
   Keywords : Control barrier functions; RRT; Discrete-time Control barrier function; Input sample; Kontrollbarriärfunktion; RRT; diskret tid Kontrollbarriärfunktion; inmatningsprov;

   Abstract : In this thesis, we consider the motion planning problem for an autonomous vehicle in an obstacle-cluttered environment approximated by zonotopes, and we propose an input sampling algorithm leveraging discrete-time control barrier function conditions (DCBF). Specifically, an optimization-based control barrier function that takes into account the geometric shapes of the vehicle and obstacles is constructed and verified. READ MORE

4. 3. Grey Box Model of Leakage In Radial Piston Hydraulic Motors

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

   Author : Niklas Ydebäck; [2021]
   Keywords : Grey box; modeling; Radial piston; Bosch Rexroth; parameter estimation;

   Abstract : This report covers the work and results of the thesis project in Mechanical Engineering from Luleå university of technology performed by Niklas Ydebäck. The objective of the thesis project is to research if it is possible, with general principles of fluid flow between components and the corresponding geometric constraints between them and just a few channels of data, to model the leakage of a radial piston hydraulic motor.

5. 4. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Fabian Maletzke; [2021]
   Keywords : turbine; blade cooling; matrix cooling; latticework cooling; CFD; heat transfer; RANS;

   Abstract : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. READ MORE

6. 5. Automated Construction- Reinforcement : Lifting Prefabricated Reinforcement Cages

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Markus Pettersson; Andreas Larsson; [2021]
   Keywords : Tied rebar cage lift; Tied connection; Connecting rebars; Finite Element Modeling; Geometric to numerical model; Integration CAD and CAE; Lyft av najad armeringskorg; Najad knutpunkt; Sammanfogning av armering; Finita Element modellering; Geometrisk till numeriskmodell; Integration mellan CAD och CAE;

   Abstract : The construction industry is moving towards an increasingly industrial production and one step towards this is to use prefabricated rebar cages. A new concept is being tested where tied rebar cages are produced on the construction site by industrial robots. READ MORE
