1. Active Flow Control for Drag Reduction of Heavy Vehicles
Abstract : This thesis considers the aerodynamics of trucks. The work focuses on the aerodynamic drag caused by the wake. Bluff-body flows are dominated by large dissipative vortex-shedding wakes with a low mean pressure compared to the high pressure on their frontal area. READ MORE

2. Particle-fluid interactions under heterogeneous reactions
Abstract : Particle-fluid flows are involved in many natural processes and industrial applications; some examples are drying, solid fuel combustion, gasification, and catalytic cracking. It is vital to understand the phenomena involved in particle-fluid flows in depth for design, predictions and process improvements. READ MORE

3. Particle-fluid interactions under heterogeneous reactions
Abstract : Particle-laden flows involve in many energy and industrial processes within a wide scale range. Solid fuel combustion and gasication, drying and catalytic cracking are some of the examples. It is vital to have a better understanding of the phenomena inside the reactors involving in particle-laden flows for process improvements and design. READ MORE

4. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling
Abstract : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. READ MORE

5. Active Flow Control for Aircrafts and Heavy Vehicles
Abstract : Bluff-body flows are dominated by large dissipative vortex-shedding wakes with low mean pressure compared to the high pressure on their frontal area. This induced pressure difference is the major contribution to the total aerodynamic drag. READ MORE
