Drag analysis of full scale cyclist model using large scale 4D-PTV: An accuracy assessment

Laser diagnostic techniques such as Particle Image Velocimetry and Particle Tracking Velocimetry to measure the flow of a fluid around an object have been in prevalence for a few decades. Typically, the fluid, whose motion is of interest, is seeded with micron scale particles and illuminated with a laser. Due to scattering inefficiencies of...

Numerical Simulations of Spirally Welded Steel Tubes Under 4-Point Bending

This master thesis investigates the response of spirally welded steel tubes under 4-point bending deformation. Through the finite element simulations of a testing the buckling behavior of sprirally welded tubes can be more clearly understood. The numerical simulation and buckling behavior of spirally welded steel tubes is discussed in this...

Non-hydrostatic modelling of large scale tsunamis

The Indian Ocean Tsunami has once again revived the discussion in the tsunami modelling community if the non-linear shallow water equations are a valid model for the propagation of tsunamis. It is suggested that the mechanism of frequency dispersion which is absent in these equations might be important in the correct modelling of large scale...
