1. 1. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances

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

   Author : Johan Germundsson; [2023]
   Keywords : master thesis; cam phaser; simulation; 1D-simulation; GT-SUITE; GT-ISE; Gamma Technologies; oil aeration; oscillations; heavy-duty; engine; phaser; cam torque; stability; cam phaser system; Scania; Scalia CV;

   Abstract : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. READ MORE

3. 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

4. 3. Modelling of a Liquid Metal Loop System : For X-ray Applications

   University essay from KTH/Hållfasthetslära

   Author : Anton Persson; [2020]
   Keywords : ;

   Abstract : A closed system of a liquid metal jet loop operating in vacuum is modelled and investigated using a commercial 1D simulation tool. Possible methods to approximate a free-falling jet in vacuum to capture the behavior of the system in 1D is investigated. READ MORE

5. 4. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System

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

   Author : Balaji Srinivasan Venkatesan; [2020]
   Keywords : 1-D simulation; System simulation; ROMAX Energy; LMS AMESim; Power loss; Hypoid gear; Power Transfer Unit; Efficiency and Drag Loss Tests; 1-D simulering; systemsimulering; ROMAX Energy; LMS AMESim; effektförlust; hypoidväxel; kraftöverföringsenhet; effektivitet och dragförlusttester;

   Abstract : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

6. 5. Analysis of the flow of secondary steam through a reheater using 3D CFD

   University essay from KTH/Mekanik

   Author : Ida Lindell; [2019]
   Keywords : ;

   Abstract : In this study 3D CFD was used to study the mass flow distribution in a reheater in a nuclear power plant. The aim was to see if 3D-modeling provide different results than traditionally used 1D-analysis. Models with detailed geometry were created for a section of the tube package in the reheater to obtain pressure drop coefficients. READ MORE
