1. Drag Reduction by means of Active Flow Control Applied on a Generic Truck A-pillar: a Numerical and Experimental Study
Abstract : 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. READ MORE

2. Experimental Study on Truck Related Power Losses: The Churning Losses in a Transmission Model and Active Flow Control at an A-pillar of Generic Truck Cabin Model
Abstract : The fight with global warming constantly forces vehicle manufacturers to innovate, in order to be able to reduce the CO2 emissions of their product. This means that marginal efficiency gains in every component are considered beneficial for total reduction of CO2 emissions. READ MORE

3. Global stability and feedback control of boundary layer flows
Abstract : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. READ MORE

4. Marine Propulsion System Performance Beyond the Propulsive Factors
Abstract : The marine propulsion system often operates in the wake of the ship it is mounted on. This implies that the propulsion system affects the flow around the hull, and the inflow to the propulsion system is dependent on the hull shape. READ MORE

5. Implementation of a flexible fiber model in a general purpose CFD code
Abstract : This work is related to the process of making pulp mats for use in hygienicproducts. One part of that process is the transportation of flexiblecellulose fibers suspended in flowing air. The fibers should be evenlydistributed on the substrate, and it is thus of high importance to avoidthe formation of fiber flocks during the transportation. READ MORE
