Aeroacoustic modeling of a LOX/CH4 rocket engine for high-frequency combustion instability prediction analyses

High-frequency combustion instabilities represent the main technical risk faced by design engineers when developing new chemical rocket propulsion systems. Such instabilities are driven by the coupling between the flames’ heat release rate and the combustion chamber’s acoustic field. As such, they can only be assessed during detailed design...

Simulation Verification and Optimization of a Vertical Axis Wind Turbine using CFD

In this research computational fluid dynamics (CFD) is used to model a vertical axis wind turbine. Well known turbulence models | i.e. the k-epsilon and k-omega SST model | are used and compared in their performance against each other and a set of experimental data. The formal research question is "What models are available for the simulation of...
