This thesis presents an in-depth investigation of the consequences of adding a second facesheet on the aerodynamic performance of acoustic liners. This is done by performing pore-resolved Direct Numerical Simulations (DNS) of a channel flow at Reτ = 500. Simulations are conducted for various dual facesheet configurations, exploring different...

While the assumption of incompressible flow has been the prevailing standard for numerical simulations of wind turbine aerodynamics, the limit of this assumption is approached as the industry progresses towards increasingly higher operational tip speeds. This thesis explores the implications of compressibility and transonic flow phenomena,...

Aerodynamics has been an important aspect of the automotive industry for decades with the wheels being a notable contributing factor. They are responsible for up to 25% of the drag in the case of a general passenger car and up to 30%-50% for an open-wheeled race car.<br/> In this research, the aerodynamic characteristics of an isolated rotating...

 Distributed surface roughness elements characterise Thermal Protection Systems (TPS) typical of supersonic and hypersonic flows. The presence of these distributed roughness elements cause an increase in drag and heat transfer.  As opposed to incompressible flow over roughness elements, there are very few experimental and numerical studies on...

In the aviation, maritime and oil&amp;gas sector, the potential benefit in yearly savings deriving from the reduction of turbulent skin-friction drag through active flow control are estimated in the millions of U.S. Dollars and million tonnes of CO2 emissions. Research in this topic has brought forward numerous techniques, offering enticing drag...
