16. Mass conservative network model for convective net flow in a complex urban geometry
University essay from Umeå universitet/Institutionen för fysikAbstract : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. READ MORE

17. Optimal placement of plasma actuators on trucks : A drag reduction study using adjoint methods
University essay from KTH/AeroakustikAbstract : The fuel consumption of vehicles plays an important environmental role and ways of improving the fuel economy is beneficial for a sustainable future. Active flow control is one method that can potentially reduce the aerodynamic drag significantly and therefore the fuel consumption. READ MORE

18. Physically Based Models for Predicting Exhaust Temperatures in SI Engines
University essay from Linköpings universitet/FordonssystemAbstract : To have knowledge about the gas and material temperatures in the exhaust system of today's vehicles is of great importance. These temperatures need to be known for component protection, control- and diagnostic purposes. Today mostly map-based models are used which are not accurate enough and difficult to tune since it consist of many parameters. READ MORE

19. Aerodynamic Wind Tunnel in Passenger Car Application
University essay from KTH/MekanikAbstract : The thesis aims to provide an evaluation on the Volvo 1/5th scaled wind tunnel regarding its potentials and capabilities in aerodynamic study. The flow quality in the test section was evaluated. The experiments were performed included measurements of airspeed stability, tunnel-wall boundary layer profile and horizontal buoyancy. READ MORE

20. Prediction of the aeroelastic behavior An application to wind-tunnel models
University essay from KTH/FlygdynamikAbstract : The work of this paper has been done during a Master thesis at the ONERA and deals with the establish-ment of an aeroelastic state-space model and its application to two wind-tunnel models studied at the ONERA. The established model takes into account a control surface input and a gust perturbation. READ MORE
