Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper comprises the study of transient dynamics of a cantilever beam in a fluid-structure interaction context. The investigation is focused on the dynamical response of a cantilever exposed to fluid flow at Re=50000, where the implicitly coupling method serves as the key function in the study.

- The predictive capability for Large Eddy Simulation (LES) for flows with unsteady separation at curved surfaces is investigated. LES with near wall modeling is applied and a range of subgrid models is evaluated for four different validation cases for which experimental flow measurement data is available. A novel model for the simulation of the effect of boundary layer tripping devices used in experiments is also proposed and evaluated. The validation focuses on the mean velocity distribution in the region of separation, as well as on the skin friction and the surface streamlines. The flow physics of separation for these four cases is illustrated and discussed in detail.

- In this work, we use large eddy simulation (LES) to study the influence of grid and subgrid model on the lift and drag force predictions of a fixed cylinder undergoing streamwise sinusoidal oscillations in a steady flow, resulting in a varying Reynolds number, Re, within the range 405

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Researchers and engineers practicing Computational Fluid Dynamics (CFD) have over the years gained a lot of experience on how to design good computational meshes. Nevertheless, for a general hull shape it is impossible to a priori know the resolution and exact design of the coarsest mesh required to obtain a certain computational accuracy. Here, the use of self-adapting schemes becomes vital. There are several methods to design self-adapting schemes. By far the most popular method is Adaptive Mesh Refinement (AMR) where the mesh is refined by adding cell points in order to split cells and reduce cell size.
