1. Urban Stormwater Treatment with Ultrafiltration and Pulsatile Fluid Flow
Sammanfattning : Stormwater can be a potential water resource if it is treated, and the quality meets the demand, depending on the application. Various nutrients and pollutants, for example microorganisms can enter stormwater and can vary depending on time and place, as the contaminants come from different sources. LÄS MER
2. Large Eddy Simulations of Complex Flows in IC-Engine's Exhaust Manifold and Turbine
Sammanfattning : The thesis deals with the flow in pipe bends and radial turbines geometries that are commonly found in an Internal Combustion Engine (ICE). The development phase of internal combustion engines relies more and more on simulations as an important complement to experiments. LÄS MER
3. Drag reduction using plasma actuators
Sammanfattning : This thesis is motivated by the application of active flow control on the cabin of trucks, thereby providing a new means of drag reduction. Particularly, the work presented strives to identify how plasma actuators can be used to reduce the drag caused by the detachment of the flow around the A-pillars. LÄS MER
4. Flow and heat transfer in a turbocharger radial turbine
Sammanfattning : In the past decades, stricter legislation has been imposed to improve fuel economy and to reduce tail-end emissions of automotive vehicles worldwide. One of the important and effective technologies adopted by the automobile manufacturers to fulfill legislation requirements is the turbocharger technology. LÄS MER
5. Shapes of pipes
Sammanfattning : Curved pipes are ubiquitous in several industrial applications and biological systems. The study of flows through these configurations is therefore of significant practical interest.In the present thesis, the modal stability of flows in both toroidal and spatially developing bent pipes is investigated to understand the onset of transition.
