  2. 1. The Hydrodynamics of Waterjet/Hull Interaction

    Author : Arash Eslamdoost; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trim angle; vena-contracta; transom clearance; net thrust; waterjet hull interaction; waterjet propulsion; capture area; exit drag; non-linear free-surface; intake drag; gross thrust; sinkage; streamtube; RANS; thrust deduction; potential flow; VOF;

    Abstract : The objective of the present investigation is to explore the physics behind the waterjet/hull interaction, and in particular the negative thrust deduction often reported in the semi-planing speed range. Another objective is to propose a validated numerical technique for computing the hydrodynamics of waterjet-driven hulls. READ MORE

  4. 2. Development of a Test Environment for Air Intake Aerodynamics of Road Vehicles

    Author : Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiator model.; wind tunnel; erodynamics; reynolds effects;

    Abstract : In the past years work on aerodynamics of road vehicles, the focus has mainly been on shaping the exterior. Recently, however, the focus has shifted towards an optimization of details. One such detail is the air intake for the cooling system. READ MORE
