  1. 1. Observation Based Modeling of Liquid Slosh in Drop Tests

    University essay from Lunds universitet/Matematik LTH

    Author : Victor Ekblad; Axl Roos; [2022]
    Keywords : Sloshing; Fluid Dynamics; Image Segmentation; 3D reconstruction; Machine Learning; U-Net; CNN; GCN; LSTM; Mathematics and Statistics;

    Abstract : Tetra Pak® is a world leading food packaging company with a large variety of paperboard beverage packages. In the development of paperboard packages, an essential component is utilizing simulation models long before physical prototypes are manufactured. This speeds up the development process and allows quick evaluation of new designs. READ MORE

  2. 2. Design of a Level Sensing System for the Propellant Tank of a Microlauncher

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

    Author : Robin Scholtes; [2021]
    Keywords : Level Sensing; Cryogenic; Microlauncher; Liquid Oxygen; Nivåavkänning; Kryogen; Mikrobärraket; Flytande Syre;

    Abstract : The present report aims to show the development process of a liquid level sensing system for the use within the propellant tanks of a launch vehicle. Whereas many recent launchers use discrete level sensing systems to indicate the amount of fuel on defined spots like fill-stop and engine cut-off, in this report a continuous capacitance based sensor probe is described.

  3. 3. Computational and experimental study of fuel leakage through a ventilation valve during various driving conditions

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sadegh Fattahi; Philip Månsson; [2019]
    Keywords : Sloshing; CFD; MULTIPHASE; fuel tank; volvo; LIU; fuel; ventilation;

    Abstract : Fuel leakage through a fill limit vent valve (FLVV) inside a fuel tank is an important factor to consider during the design of a new tank. The performance of the carbon canister which absorbs the hydrocarbon can be compromised if fuel manages to escape through the valve, so called Liquid Carry Over (LCO) and thus not fulfilling the fuel emission requirements.

  4. 4. Numerical Investigation of Spin-Up of a Fluid-Filled Cylindrical Tank

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Dennis Kröger; [2018]
    Keywords : Sloshing; Rotational fluid; tank; European Space Agency; High Reynolds number; Ekman pumping; FINE Open; Numeca; Technology and Engineering;

    Abstract : This report is an investigation on how well fuel sloshing in a rotating cylindrical tank can be modeled numerically. The investigation is motivated by the need to understand the fuel sloshing in the new Ariane 6 rocket developed by the European Space Agency. READ MORE

  5. 5. Exprimental Study of Spin-Up of a Fluid-Filled Cylindrical Tank

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jakob Svensson; [2018]
    Keywords : CFD Computational Fluid Dynamics Experimental Physics Spinning Spin Flow Laser Image Analysis Acceleration Ekman Boundary Layer Rossby Vortex Parabola Particles; Physics and Astronomy;

    Abstract : To ensure safety on upper stage rockets, the fluid dynamic phenomenon known as sloshing in the liquid propellant tanks needs to be understood. CFD is a relatively cheap tool, but studies by Schmitt [7] suggest that models currently used for simulations do not predict the flow behavior. READ MORE
