  2. 1. Long-Term Simulation of Coastal Evolution

    Author : Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

  6. 4. Operating conditions impact on flow and acoustics in turbocharger compressors

    Author : Emelie Trigell; Mihai Mihaescu; Mats Åbom; Lisa Prahl Wittberg; Damian Vogt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; compressor; LES; surge; rotating stall; flow instabilities; inlet recirculation; aeroacoustics; acoustics; Teknisk mekanik; Engineering Mechanics;

    Abstract : Fluid machines are an integral part in energy conversion with applications from pumps, fans, propellers, compressors and turbines. In the automotive industry, turbochargers are commonly employed to counteract the effect of engine downsizing. READ MORE

  7. 5. Perspectives of Aerodynamic Drag and Cooling Airflow for Heavy-Duty Trucks - Reconsidering European Total Length Legislation

    Author : Helena Martini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling airflow; CFD; under-hood design; soft nose; truck-trailer combinations; inlet duct; outlet duct; aerodynamic drag;

    Abstract : Increasing fuel prices and constantly lowered emission legislation forces the vehicle industry to develop new methods for propelling vehicles and to optimize existing technology. Trucks constitute a significant proportion of the transportation system; consequently it is of great importance to ensure as low an impact as possible on the environment. READ MORE
