Numerical study of the interaction between a sonic transverse jet with an oblique shock wave in a supersonic crossflow

A series of numerical simulations was executed using the high-performance cluster at TU Delft's Aerospace Faculty. The primary objective was to gain deeper insights into the intricate dynamics of a sonic transverse jet in a supersonic crossflow with an oblique induced shock wave, especially concerning mixing. These simulations delved into the...

Modeling and characterization of non-ideal compressible flows in unconventional turbines

The vast majority of energy conversion systems currently makes use of fossil fuels, whose combustion generates harmful greenhouse gases. Transitioning to renewable energy sources is thus paramount to limiting the environmental impact of human activities on the climate. In this regard, the harvesting of wasted thermal energy constitutes a...

Rotating Discs Actuators: Direct Numerical Simulation for Turbulent Skin­Friction Drag Reduction

In the aviation, maritime and oil&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...
