  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    University essay from KTH/Teknisk mekanik

    Author : Ziyi Liu; [2024]
    Keywords : Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Abstract : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. READ MORE

  3. 2. Efficient FE Modeling of Large Casted Parts

    University essay from KTH/Maskinkonstruktion

    Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

  4. 3. Development of HVAC simulations for truck cabins using OpenFOAM

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Junaid Haider; [2023]
    Keywords : Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

    Abstract : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. READ MORE

  5. 4. CFD simulation of dip-lubricated single-stage gearboxes through coupling of multiphase flow and multiple body dynamics : an initial investigation

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Nasir Imtiaz; [2018]
    Keywords : transmissions; churning losses; CFD; STAR-CCM ; FZG gearbox; planetary gearbox; RBM; MRF; unsteady framework; VOF; immiscible; overset meshing technique;

    Abstract : Transmissions are an essential part of a vehicle powertrain. An optimally designed powertrain can result in energy savings, reduced environmental impact and increased comfort and reliability. Along with other components of the powertrain, efficiency is also a major concern in the design of transmissions. READ MORE

  6. 5. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Bona Ryan; [2017]
    Keywords : Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Abstract : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. READ MORE
