  1. 6. Interscale transport of Reynolds stresses in wall-bounded flows

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gioele Ferrante; Andres Morfin; [2019]
    Keywords : Reynolds Stress; Zero-Pressure Gradient Turbulent Boundary Layer; Turbulent Couette Flow; Inverse Interscale Transport; Energy Cascase; Wall-bounded Flows; Direct Numerical Simulation; Large Eddy Simulation.;

    Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.

  3. 7. Evaluation of a digitial displacement pump in a load haul dump application

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jayasurya Madhusudanan; [2019]
    Keywords : Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

    Abstract : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. READ MORE

  4. 8. Driver model for a software in the loop simulation tool

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

    Author : Yue Zheng; [2019]
    Keywords : HDV Heavy duty vehicle ; simulation tool; Driver model; longitudinal velocity controller; HDV tungt fordon ; simuleringsverktyg; förarmodell; longitudinell hastighetsregulator;

    Abstract : For this project, a Software-In-the-Loop (SIL) simulation tool is used at Scania (“VTAB” – Virtual Truck and Bus), which simulates the submodels of the mechanical vehicle components together with the real control units. The simulation tool contains the following submodels: Engine model, Drivetrain model, Drive cycle model, Restbus model, and Driver model. READ MORE

  5. 9. Control of a Hydraulic Hybrid System for Wheel Loaders

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Christopher Reichenwallner; Daniel Wasborg; [2019]
    Keywords : EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Abstract : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.

  6. 10. Design and Fluid Simulation of a Fluidic Growth Chamber

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Pranav Bapat; [2019]
    Keywords : ;

    Abstract : Filamentous fungi are of interest for biotechnologists particularly because of thefungi’s ability of producing commercial products after undergoing certain industrialprocess. Although because of the complicated and intricate internal mechanism ofthe fungi there are certain aspects which need to be studied to maximize the produc-tion output. READ MORE
