  1. 1. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Matilda Tiberg; [2022]
    Keywords : Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

    Abstract : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. READ MORE

  2. 2. Aeroengine transients in altitude test facility

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

    Author : Baptiste VILLENEUVE; [2022]
    Keywords : ;

    Abstract : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. READ MORE

  3. 3. Dynamic Modeling of Target's Cooling Systems

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Maximilian Cahlin; [2021]
    Keywords : Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

    Abstract : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. READ MORE

  4. 4. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Oskar Kuoppala; [2021]
    Keywords : CFD; Cavitation; Water Hammer;

    Abstract : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. READ MORE

  5. 5. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Sohail Anwar; [2020]
    Keywords : Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Abstract : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). READ MORE
