  1. 16. Analysis of the intake grill for marine jet propulsion

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marcus Söderberg Jansson; [2019]
    Keywords : Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

    Abstract : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. READ MORE

    Abstract : Transportations role in society is increasingly important and today it has a prominent role in business, citizens lives as well as in the world economy. The increasing globalization and urbanization puts significant pressure on the existing transport system, with increasing demand for high-speed travel. READ MORE

  5. 19. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

    University essay from KTH/Bro- och stålbyggnad

    Author : Niklas Wiberg; Jasmin Halilovic; [2018]
    Keywords : Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

    Abstract : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.

  6. 20. CFD analysis of stepped planing vessels

    University essay from KTH/Mekanik

    Author : Toni Kokkonen; [2018]
    Keywords : Computational Fluid Dynamics CFD ; Ship hydrodynamics; Planing hull; Stepped hull; STAR-CCM ; Overset mesh; Volume of fluid VOF ; Reynolds averaged Navier-Stokes equations RANS ; Dynamic instabilities;

    Abstract : High speed planing hulls are currently widely used for example in recreational and emergency vessel applications. However, very little CFD research has been done for planing vessels, especially for those with stepped hulls. A validated CFD method for planing stepped hulls could be a valuable improvement for the design phase of such hulls. READ MORE
