    Detta är en avhandling från Chalmers University of Technology

    Författare :Jan Östh; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle Aerodynamics; Numerical Simulations; Large Eddy Simulation; Reduced-Order Modelling;

    Sammanfattning : In this thesis several simulations have been carried out aimed at improving the knowledge of vehicle aerodynamics and improving the flow around vehicles with respect to the aerodynamic drag. Five flows around different simplified vehicle models have been considered in five appended publications. LÄS MER
