1. Acoustic Manipulation of Particles and Fluids in Microfluidic Systems
Abstract : The downscaling and integration of biomedical analyses onto a single chip offers several advantages in speed, cost, parallelism and de-centralization. Acoustic radiation forces are attractive to use in these applications since they are strong, long-range and gentle. READ MORE

2. Turbulence modeling of compressible flows with large density variation
Abstract : In this study we highlight the influence of mean dilatation and mean density gradient on the Reynolds stress modeling of compressible, heat-releasing and supercritical turbulent flows.Firstly, the modeling of the rapid pressure-strain correlation has been extended to self-consistently account for the influence of mean dilatation.

4. High order difference approximations for the linearized Euler equations
Abstract : The computers of today make it possible to do direct simulation of aeroacoustics, which is very computational demanding since a very high resolution is needed.In the present thesis we study issues of relevance for aeroacoustic simulations. Paper A considers standard high order difference methods. READ MORE
