  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

    Keywords : Autonomous Driving; Model Predictive Control; Stochastic Model Predictive Control; Trajectory Planning; Uncertainty; Road Crosswind;

    Abstract : Trajectory planning constitutes an essential step for proper autonomous vehicles’performance. This work aims at defining and testing a stochastic approach providingsafe, length-optimal and comfortable trajectories accounting for road, model anddisturbance uncertainties. READ MORE

  5. 4. Study of the Fan Forced Response due to Crosswind

    University essay from KTH/Aerodynamik

    Author : Victor Guillard; [2014]
    Keywords : ;

    Abstract : Structures of an aircraft engine are not completely rigid. Therefore when they are subjected to aerodynamic loading, those structures will deform elastically and their shape will change, especially fan blades because of their size. READ MORE

  6. 5. Crosswind assessment of trains on different ground configurations

    University essay from KTH/Järnvägsteknik

    Author : Nachiyappan Venkatasalam; [2013]
    Keywords : Crosswind; ICE3; true flat ground TFG ; single track ballast and rail STBR ; atmospheric boundary layer ABL ; AeroTRAIN; CFD.;

    Abstract : Cross wind analysis is one of the important safety measures for rail vehicle certification. The objective of this study is to identify which vehicle certification ground setup, true flat ground (TFG) or single track ballast and rail (STBR) represents a more realistic ground setup with atmospheric boundary layer (ABL) wind inlet and also to represent an embankment scenario.
