1. Active Flow Control for Reducing Drag on Trucks: from Concept to Full Scale Testing
Sammanfattning : There is no doubt that road vehicle transportation is needed to improve efficiency, to reduce power consumption and to contribute to a sustainable mobility. Aerodynamics plays a crucial role in this, and its optimization can have a significant impact on fuel efficiency. LÄS MER
2. Drag Reduction by means of Active Flow Control Applied on a Generic Truck A-pillar: a Numerical and Experimental Study
Sammanfattning : The overall goal of this thesis is to isolate and control the flow mechanism characterizing the flow separation occurring at the A-pillar of a truck. The study aims to gain knowledge of the flow physics of the separation mechanism, and to eventually suppress the afore mentioned separation by means of an Active Flow Control. LÄS MER
3. Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars
Sammanfattning : In this thesis several simulations have been carried out aimed at improving the knowledgeof vehicle aerodynamics and improving the flow around vehicles with respect to theaerodynamic drag. Four flows around different simplified vehicles have been considered. LÄS MER
4. Unsteady Numerical Simulations and Reduced-Order Modelling of Flows around Vehicles
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 theaerodynamic drag. Five flows around different simplified vehicle models have been considered in five appended publications. LÄS MER
