1. Deviation From Local Equilibrium During the Austenite to Ferrite Transformation in Steel-A Modelling Approach
Abstract : This thesis highlights the role of phase interfaces on phasetransformations in metallic materials. The deviation from localequilibrium at the moving phase interface has been analysed interms of solute drag theory and finite interface mobility. Inparticular the planar growth of proeutectoid ferrite fromaustenite in steel has been studied. READ MORE

2. Passenger Car Wheel Aerodynamics
Abstract : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. READ MORE

3. Aerodynamics of two trucks driving in close-proximity
Abstract : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. READ MORE

4. Analysis of the Base Wake on Passenger Vehicles
Abstract : Car manufacturers are presented by a continuous increase in fuel prices and by ever more strict legislations regarding CO2-emissions. Decreasing the driving resistance and hence the fuel consumption of their vehicles helps to improvetheir market share. READ MORE

5. The Hydrodynamics of Waterjet/Hull Interaction
Abstract : The objective of the present investigation is to explore the physics behind the waterjet/hull interaction, and in particular the negative thrust deduction often reported in the semi-planing speed range. Another objective is to propose a validated numerical technique for computing the hydrodynamics of waterjet-driven hulls. READ MORE
