  1. 1. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Emil Vejlens; Dylan De Jourday; [2022]
    Keywords : Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

    Abstract : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. READ MORE

  3. 2. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  4. 3. Visualization and Quantification of Helical Flow in the Aorta using 4D Flow MRI

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Filippa Gustafsson; [2016]
    Keywords : Helical flow; Helicity density; LNH; 4D Flow MRI; geometry of the aorta;

    Abstract : Due to the complex anatomy of the heart, heart valves and aorta, blood flow in the aorta is known to be complex and can exhibit a swirling, or helical, flow pattern. The purpose of this thesis is to implement methods to quantify and visualize both the speed of helicity, referred to as the helicity density, and the direction of helicity, which is measured by the localized normalized helicity.

  5. 4. PIV Investigation of the Intake Flow in a Parallel Valves Diesel Engine Cylinder

    University essay from KTH/Mekanik

    Author : Jean Rabault; [2015]
    Keywords : Admission stroke; Flow in cylinder; Swirl motion; Admission channels;

    Abstract : Preliminary designs for the cylinder heads of Scania’s next generation Diesel Engine have been investigated by the means of PIV measurements on a steady test rig. General structures present in the flow have been investigated, with a specific focus on Swirl motion due to its well documented impact on combustion efficiency and pollution generation. READ MORE

  6. 5. Flow simulations with relevance to a centrifugal compressor and the eect of the inlet geometry

    University essay from KTH/Mekanik

    Author : Ander Eza; [2015]
    Keywords : ;

    Abstract : Turbocharging the internal combustion engine is one of the most effective ways to reduce the fuel consumption and fulll the green house gas emissions requierements. Nevertheless, this techinque has some limitations that need to be addressed in order to improve the turbocharger performance. READ MORE
