1. Dynamics of bubbles across scales
Abstract : This thesis presents numerical investigations of bubbly flow phenomena across a wide range of relevant spatial and temporal scales. The aim is to increase our understanding of a great variety of underlying phenomena and to facilitate improved predictions of bubbly flows at all relevant scales. READ MORE

2. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer
Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

3. Gas Mixing in a Circulating Fluidised Bed Boiler
Abstract : The present thesis is a study on the gas-mixing behaviour in a circulating fluidised bed (CFB) boiler. The aim is to describe how gas is spread in different regions of a CFB furnace and to explain variations in the mixing rate under different operating conditions. READ MORE

4. A Multi-Scale Approach To Adhesive Mixing
Abstract : Adhesive particle mixing is a fundamental process in many applications, especially in dry powders for inhalation. Despite its importance, a mechanistic process description for designing the structure of interest is still lacking. READ MORE

5. Numerical studies of turbulent flames in wall-jet flows
Abstract : The present thesis deals with the fundamental aspects of turbulent mixing and non-premixed combustion in the wall-jet flow, which has a close resemblance to many industrial applications. Direct numerical simulations (DNS) of turbulent wall-jets with isothermal and exothermic reactions are performed. READ MORE
