17. Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves
Abstract : In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power. READ MORE

18. Numerical prediction of propeller induced hull pressure pulses and noise
Abstract : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. READ MORE

19. Power Extraction in Military Aircraft
Abstract : Military aircraft require more and more power. Pneumatic and hydraulic systems are being replaced by electrical equipment and new, power consuming equipmentis introduced in the aircraft. Increased power extraction brings new challenges for the aircraft jet engine, both in terms of operability and with regards to engine performance. READ MORE

20. Numerical Analysis of Cavitation-Induced Erosion in High-Pressure Fuel Injectors: under static and dynamic lift conditions
Abstract : Fuel injection systems are crucial for all modern combustion engines. These systems often operate under very high pressures to ensure fast spray breakup for optimal fuel air mixing leading to efficient combustion in order to meet strict emission standards. READ MORE
