  1. 16. Two-dimensional roughness and Tollmien-Schlichting waves: a study on transition

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Derek Micheletto; [2020]
    Keywords : ;

    Abstract : Two-dimensional (2D) roughnesses induce premature transition to turbulence in laminar boundary layers by amplifying the disturbances in the flow and promoting the development of non-linearities. The present thesis aims at furthering our understanding of this phenomenon's underlying mechanisms and elucidating the effects of the different geometrical parameters of the roughness' cross section.

  3. 17. Fundamental combustion properties of alternative fuels for energy transition

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Yijing Mao; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. READ MORE

  4. 18. Analysis of Cooling System and Its Influence on Magnetic Flux Density in a Motor

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Ronaldo Gustav Pangihutan Hasibuan; [2020]
    Keywords : Generator; Motor; Permanent Machine;

    Abstract : After Michael Faraday invented the magnetism theory in 1821, the application of the permanent magnet machine was rapidly developed. The permanent magnet synchronous machine is one of the popular applications of electromagnetic theory, which is implemented in most electric vehicles nowadays. READ MORE

  5. 19. Motion of a Gaussian Through a 2D Dilute BEC Droplet

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Zhanna Kuhrij; [2020]
    Keywords : Bose-Einstein Condensate; BEC; Droplet; Dilute; Liquid; Quantum Mechanics; Fluid Dynamics; Superfluid; Superfluidity; Quantum Fluctuations; LHY-correction; Flow patterns; Gaussian; 2D; Vortices; Gross-Pitaevskii Equation; Physics and Astronomy;

    Abstract : In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. READ MORE

  6. 20. Demonstration station for open water channel flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : David Bayat; Fabian Grönvik; [2020]
    Keywords : ;

    Abstract : Once a year an event is being held at the fluid physics lab at KTH. One of the main purposes of this event is to awaken an interest in the visiting students from other universities, by demonstrating fluid physics phenomena. Showing the transition from laminar to turbulent flow in an open water channel is one of the demonstrations. READ MORE
