1. Flow measurements related to gas exchange applications
Abstract : This thesis deals with flow measuring techniques applied to steady and pulsating gas flows relevant to gas exchange systems for internal combustion engines. Gas flows in such environments are complex, i.e. they are inhomogeneous, three-dimensional, unsteady, non-isothermal and exhibit significant density changes. READ MORE

2. Flow Measuring Techniques in Steady and Pulsating Compressible Flows
Abstract : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. READ MORE

3. Approaching a practice for transient CFD simulations of vortex flow meters
Abstract : The usage of Large-Eddy Simulations (LES) in industrial applications makes it possibleto study transient phenomena. The aim of this work is to find a reliable and accurateapproach to transient studies of the internal flow field in a vortex flow meter. READ MORE

4. Mixing and Evaporation at the Cloud Edge and Angular Dynamics of Small Crystals in Viscous Flow
Abstract : How liquid water in atmospheric clouds distributes over droplets of different sizes is important for the initiation of rainfall, and for the optical properties of the atmosphere. Droplet-number densities and droplet-size distributions change rapidly at turbulent cloud edges, where mixing of cloudy and dry air causes cloud dilution and droplet evaporation. READ MORE

5. Robust gas flow metering under extreme industrial conditions
Abstract : In this thesis, a different method for creating acoustic pulses that can be used in the ultrasonic spectrum is proposed. The aim is to develop a robust and reliable system that uses ultrasonic techniques, such as transit time or sing-around, to measure gas flows in extreme environments. READ MORE
